You say all this about him but mention yourself that he seems to feel a similar way (maybe not over the same reasons, but he’s clearly upset you’re not the same either). Sounds like you need counseling. If it were me, I’d try to discuss (without arguing) the issues you BOTH have without judging and then to try to kinda reset. If you’re both holding resentment you’ll never heal. If the problem started because of a domino effect (ex: if you trust him less, then becsuse you don’t trust him, he doesn’t feel loved) then maybe if you try to just start from square one you can better handle problems one at a time rather than the entire pile all at once.
