Delayed ejaculation at a loss

My Bf has struggled with delayed ejaculation for years while (beds together 8yrs) During the past few years I have had major issues with abnormal bleeding including a surgery and continued issues, which doesn’t put me in the mood. We have sex about 1-2x a week when I am not bleeding but sometime 2-3 weeks in between if I am bleeding. He cums rarely. When I ask what I can do to help he gets mad and won’t talk about it saying I don’t care and that he can come we just don’t have regular enough intercourse to keep it up. We have talked about doing other things but when I offer he says it’s out of obligation and not because I want to and says “no”.

Then he says I don’t like anything he likes so he won’t ask me to do it anymore (some positions aren’t as comfortable depending on position of cervix, which he doesn’t get). After that he says he won’t even try to orgasm himself anymore because if he does it once it may not happen again for a long time which makes it worse. I am getting depressed idk what to do.

If we talk about it. It ends up him angry and me crying. When we have sex it is great but he just can’t cum and eventually gets upset and stops. We always say we will try again later that day but don’t due to life and responsibility. (So he blames me for that) I told him we can set up times to “play” and he doesn’t like it because it’s “scheduled”. He is on lots of medication, adhd, ptsd, chronic back pain, and traumatic brain injury. All medications say this is a side effect but he doesn’t seem to acknowledge it. I know the rest all affect this as well. At a loss right now. I know he won’t go to counseling Ana no insurance currently so doctor isn’t an option as they are super expensive for this stuff.

As time goes on I feel defeated due to rejection and him not wanting to try further to cum. Feel like I am damn if I do and damn if I don’t try at this point. Beyond this 10% of our lives everything else is great and he truly is my soul mate.
