My very loving husband of 21 years (since I was 18) came out as bi to me 1 month ago.  He said he always felt that something was missing and that he had supressed this feeling since he was a teenager. Originally from Brazil, we met shortly after he came to the states when we were very young.  We have been pregnant 6 times, and have 3 living children, 1 with Cerebral Palsy and 1 with Autism.  We are very romantic and passionate together and both love each other and we both say we are each others soulmates.  
When he told me, he was very respectful about it.  He had picked me up from the airport after a very long work trip and were alone in a hotel room for the night together, away from kids/family.  He cried, he was only just started to accept who he is.  He told me how much he loves me and is in love with me and wants to make this marriage work and not leave.  However, he is inisistant on sleeping with Men on the side but had not done anything yet.
I had a very hard time at first with everything, how could he be this after 21 years together?  I felt like I was not enough, that I had done something wrong.  I did not and still dont want him going out and cheating on me with men so I thought a 3 some with a bi men would be better.  He was reluctant because he didnt want to do things in front of me but we ended up doing it together.  It was hard to see him do things with a man but was easier then I thought it would be.  He had the harder time seeing me with someone else.  It has been 2 weeks since the threesome and he is still wanting to sleep with men on the side on his own.  I dont know if I can accept this.  To me it is cheating.  We are both seeing our own therapist now and have started to see a LGBTQ+ marriage therapist.  Does anyone have any experiences with a bi husband and if they are okay with them going out on the side for this?  
The most suprising thing about him coming out....we have had relations everyday since he told me and it has be
