@Strawberry, I wouldn’t say he’s being an asshole. He explained he has PTSD and he cannot be around you when it gets bad.
Translation... he cannot handle the additional relationship stressors and/or your emotions when he cannot handle his own. This is fairly typical in PTSD relationships. Some sufferers isolate as a coping mechanism when they get overwhelmed.
Relationships are stress. Your needs are stress. If you argue it’s stress. You needing contact and reassurance are stress. Plans are stress... even good stress is still stress. He has a broken stress response.
This is an analogy we use in the supporter section. Imagine your BF is swimming upstream in the middle of a deep raging river. He’s swimming with all his might, fighting to keep his head above water. Now your wading in the shallows, dog paddling around, hollering at him to come swim with you. Why won’t he answer you? He must not love you if he doesn’t come swim with you right now. The reality of the situation is he’s trying not to drown, and he cannot stop swimming to pay attention to you.
When he is symptomatic and isolates to cope, he is just hanging on trying to keep his head above water.
Don’t take it personally, and look at the big picture. He needs a little space to feel better. He doesn’t hate you. He’s not ignoring you to be malicious. He doesn’t feel good and just needs a few days to work through it. Stop considering it a slight against you, and consider the fact that he’s working through PTSD symptoms. Look at giving him that space as a loving act. “I love you enough to *NOT* make this a relationship issue, or about me. I want you to feel better, and if you need a few days, I will respect that”. See the shift?
If you need constant contact in a relationship and a lot of attention from your partner, a PTSD relationship with a sufferer who needs to isolate may not be for you. This is probably reality setting in after the honeymoon period, so I’d bet this is typically how he handles stress. In other words, he’s going to do this a lot. If that’s not something you can handle, that’s something to consider. Not everybody wants a relationship like this, and that’s perfectly valid and OK. On the other hand, if you think you can handle this, then you need to get over the isolation periods in a big way if you want to stay sane.
I get it, it sucks. My partner isolates. We’ve been together 8 years, and he still has to have some alone time to cope. I actually kind of enjoy the alone time myself. It gives me a chance to do things that I enjoy that he cannot handle (like loud, crowded and/or girly stuff).
It doesn’t mean you have to sacrifice everything... for instance, it’s OK to not be OK with extended periods of no contact (like weeks) or, say, ignoring you in an emergency situation (and I mean a real emergency, not little everyday crises). These would be boundaries to discuss when he is feeling better.
