Has anyone struggled with losing attraction to their newly trans partner? If so, what did you do?

My husband has been transitioning and on hormones for about a year. I've noticed that lately, his personality has changed a lot and he's becoming very narcissistic. He talks a lot about being grateful for my understanding and support, and if I need anything just to tell him. But when I do, I feel like he spins whatever I say into a pity party for himself. For example, he asked to spend $120 on clothes and shoes for himself this week and I said that was too much, we have bills due. I said we could afford to spend $60-80, could he trim his cart down a little? He said he really needed these outfits and he hates his "manly" sneakers, can't we trim something else?
We are already paying over $200 a month between his hormones, plume membership and therapy appts, plus random $100 shopping sprees for tucking underwear or stickers (he legit spent $100 on trans awareness stickers, like wtf!), the worst part is I usually find out about it afterward. We have 4 kids and cannot afford this extra spending. I can't even tell you the last time I bought clothes or shoes for myself like that!
My old husband would never put us into debt on purpose for something frivolous like this, it's like every week there's something new that he absolutely needs to feel affirmed.

His complaints vary from the kids not washing his favorite lunch containers or shaker bottles, or they ate his box of Nutty Bars before he could get one, or (my personal favorite) our puppy purposely chews up anything HE leaves on the couch.. she will chew up food wrappers if they are left out, and he has a hard time cleaning up after himself so of course she's gonna get to it! Ugh it's so frustrating, he's like a teenager. Everything everyone does is on purpose against him.

Im finding him less attractive every time he complains, I just want to roll my eyes and tell him to get over it. But I'm doing my best to stay positive and help him through this, even though it's killing me.
I bought a workbook for partners of trans people to help guide me through this and so far it's been very good for me. I'm trying not to think too much about the future and just live day to day with him as he is now. I want to make this work as long as possible, but knowing eventually we won't be sexually compatible has been so depressing.

Does anyone have advice on how to get through this rough patch? I know long term relationships have highs and lots, maybe my attraction will come back?
