I have been watching it. It’s imperfect at times, but as a TV series it’s actually better than most. In the beginning I was being hyper critical, because some aspects glossed over my reality — but eventually I had to admit, they would never make a realistic series about my life because it would be so miserably depressing nobody would ever watch it.

So I watched, and it was at a time when I was just desperately lonely carrying this secret around, and I finally figured out why I was so hooked on it. It was just the idea of having a best friend who knew everything, and knew exactly what I was going through because she was going through the exact same thing. It was the idea of having someone there to hold my hand at the worst moments because she knew exactly what I was feeling. I wouldn’t have to put on a false cheerful face all the time. I realized that I’m watching the two of them living together in a beautiful beach house, and I would just about kill to have a best friend like that.

The latest season has a plot twist that was very difficult to watch: a house next door to the two men is bought by a young couple, and the husband is obviously gay, and the question comes up of whether the guys should intervene in some way. I haven’t seen how they deal with this, but I find it very hard to watch without crying.

I'm in the refuse to watch it camp, too.  Maybe it's just too soon. 
 

I have watched the first season of "Grace & Frankie" (DVD set from library. Definitely would not waste my hard-earned money to buy them.)
    The Michael Sheen character seems most like my ex. in that he seems self-absorbed, not caring what damage the relationship does to others, including "Sol".  Caught myself wishing my X was more like Sol, who seemed to genuinely love Frankie. When she needed comforting, he gave it; the "sleeping together" after divorce seemed to cause him great angst. I question how much angst / guilt he felt while he was still married to Frankie & involved with Robert. 
All in all, it seems the men are among those who are "privileged" and accustomed to having what they want, when they want. They had MOMs when it was more economical, convenient, necessary for them; then when it became inconvenient & unnecessary they wanted out. Imagine trying to build a law career as a gay man 40 years ago, when homosexuality was considered a "disease" & illegal. Or imagine maintaining the law firm when they decided to act on their feelings.  No, the cowards (that is my word for anybody who refuses to tell the truth because he is afraid of adverse results to himself) chose to continue the facade until gay marriage was acceptable. These guys are in their 70s, with adult children. Now they want to celebrate their retirement years with each other?  The wives probably expected, for 40 years, to enjoy their retirement years with their husbands.  The difficult years of child-rearing had been done successfully.
  As I write this, I realize  that I too expected to spend my late middle-age with my husband, the father of our children.  Instead, for the past 18 years, I have had to occupy myself with upgrading my marketable skills, then deal with being told I am "too old" to begin a career that I had been working on before I was distracted by marriage (34 years earlier). My X is 62 and seems to be enjoying himself with (according to our children) a man who speaks no english in the south of France (the X is english/french bilingual).
   Oh, by the way, walkbymyself, when my X acted in, "No Sex Please, We're British", shortly after he told me, "I want to explore my homosexuality", I insisted on going to see that play in a local theatre. What shocked me most was the way he kept his composure when 2 buxom women where stroking his face & fondling him. Whenever I touched him in such an alluring way, he'd stop me, saying, "That's too ticklish!" and squirm out of reach. But in the play, he stayed unmoving.!!  I felt quite sick and yes, jealous.
   Back to "Grace & Frankie", to me, the show is as "real" as "Friends", "Seinfeld" and other sitcoms: not real, but what some people imagine.... Oh, and when the 2 men are writing the vows they plan to state during the wedding, I wondered what promises they made to their wives 40 years earlier. How honest & trustworthy were they then? Or do they believe promises are temporary, until something or someone else comes along successfully tempting them?  What do they believe the word "vow" means?  According to the dictionary, a "vow" is a solemn oath, a pledge, a covenant.
   If these 2 men could so easily break their vows to their wives (after only 20 years), how easy would it be for them to break to each other?  Why bother to make "vows" to each other?  Or perhaps, being in their 70s, there is little chance of them having the time to break the vows?? 

I thought the show tried to be sensitive and at least in the womens' experiences, it did portray the feelings of betrayal and anger and self-doubt.  I don't think the two men are true-to-life.  

I was taken with the first season because it so directly addressed a very difficult and painful issue, and in each episode it was like one isolated step at a time got examined: the impact of a husband cutting off his wife's credit cards was an entire episode.  Having to go to a public event with your STBX was one episode.  The later episodes (in later seasons) are more like soap operas, but the early episodes were more true to life for me.

I realized after a while that what I watched for, was the sense that in my worst possible moments of isolation and pain, I would have given my right arm to have a best friend who knew exactly what I was going through because she was going through the same thing.  I imagined what it would be like for us not to have money woes, and we could share a beach house together with a big open floor plan and a modern kitchen and listen to the sound of the waves in La Jolla while we worked through all the pain and confusion.

That's what I was hooked on.
