Idk what to do 😞

A little back story: My husband and I have two sons. One will be 2 in November and the other will be 1 month tomorrow. I’ve been dealing with PPD, as well as a ton of stress from our life. We live with my mom right now and are supposed to be moving out in October ish, but I’m on maternity leave, my husband insists I don’t go back, but yet he can’t keep a job for more than 2 weeks. My anxiety is always so high because I don’t want to end up with no where to move and no income. My husband has started arguments in the last couple weeks saying that I don’t pay attention to him and that I don’t like having sex with him anymore which started before baby (the accusations), and has moved onto him complaining that I don’t orgasm anymore. I honestly don’t know why I can’t, I assume stress and depression.. but I’ve never been this way. We’ve always had sex a lot, every day, usually multiple times, and I almost always can have an orgasm, at least with him eating me out if all else fails. But for the last couple months even if he goes down on me for 30-60 minutes, I cannot orgasm no matter how good it feels or how close I get. This has led to him insisting that he “knows” I’m cheating (I’m NOT, I could never do that to someone I love) because apparently I’m “too sexual to just accept average sex.” Like what?? He accuses me of it almost daily and I know with his BPD his insecurities have risen, but it’s seriously driving me insane. It’s made it so that when we go to do anything sexual, I get so anxious that he’s going to get mad if I can’t orgasm that I just can’t focus or enjoy it and I spend the whole time worrying about trying to come, or I just try and avoid the sexual stuff all together. I have absolutely no idea what to do anymore because on top of only getting 2-5 hours of sleep a day/night, I’m being accused of cheating and not loving him everyday, he complains about the sexual activity, our son is in terrible 2s, I’m stressed about money, I’m stressed about getting out of my moms house (I hate it here and have wanted out since we had to start staying here), and I just want to give up on everything.

Has anyone else ever struggled with not being able to orgasm?? Did you solve your issue somehow?
