Hello kiwinz: You don't mention, in your post, if you & your partner are living together. I presume you are. That, of course, makes this situation much more complicated. If you were not, I would say just back out of this situation & give your partner time to resolve what is going on. But, assuming you live together, that makes it more difficult.

Still, I think the best thing you can do is to simply back off & allow your partner whatever amount of space & time he needs in order to resolve this situation. Your partner is certainly being inconsiderate & perhaps, one might say, even verbally abusive. How he's treating you is inappropriate. But the reality is you can't make him do differently.

Ideally, perhaps, your partner would get some individual therapy for himself & / or participate in some couples counseling with you. However, from what you wrote, I'm thinking there's probably not much likelihood that is going to happen. Assuming that's the case, you simply have to take care of yourself. Perhaps seek some individual therapy for yourself. Perhaps try to find enjoyable things to do with friends to fill your leisure hours during this time.

Hopefully in the not-to-distant future, this will all be resolved & you & your partner can recoup your normal lives together. It is possible though too that this distressing event may prove to be a relationship breaker for the two of you. Hopefully that will not be the case. I don't know if that is something that is in the back of your mind. It may be that you'll need to avail yourself of some individual therapy services in order to sort through your feelings. I wish you well...
