@Josh4757, I'm just going to be honest about what I've observed in your threads. Please, take it in the spirit it is offered, which is one of support and understanding.
I think you have somehow slipped into panic mode about your girlfriend's diagnosis. I think that because of how much internal pressure I can read in your posts, the kinds of answers you are looking for. I can tell you care about this girl very, very much.
People are basically animals - all of us. And we read an
enormous amount of non-verbal communication. I suspect that your girlfriend can feel your panic and desperation, and if there's one thing a drowning person doesn't want, it's someone else flailing right next to them.
Whatever stage her therapy is at, or where she is in her diagnosis -
whatever it is - she's going through a tough time. And of course, you want to be there for her. I think in making sure she knows that you are there for her, you are unintentionally clutching on, and (to follow the swimming metaphor), she's going to need to push you away so she can just try and deal with her own situation. It's hard to keep your head about water with PTSD.
I'm a sufferer, and I'm a woman, so I'm talking from those standpoints. Most of the time I've been dealing with my PTSD, the last thing in the world I want is to talk to someone who doesn't have it but is reading all about it. You'd think that would feel like a good thing, to talk to someone who has immersed themselves - but I don't think it feels like a good thing to everyone. I'd wager about half of us would feel a combination of trapped and angry: trapped because someone has found a box to put us in, and angry because it can feel insulting to have someone think they understand what you are going through when you don't have a clue yourself.
I'd suggest you really take that hiatus you are supposed to be taking. Keep it light when you talk to her. Don't pressure her to reassure you that the relationship is still intact. (I think you are doing that without realizing it). Give her real space.
Small anecdote: I was still in a relationship when I started having a very hard time with things. In my case, the relationship also had its problems. When I asked for a break, he agreed, except he tried to insist on regular email communication, because, as he said, "otherwise how would I know how you were doing?"
He was missing the point. The point was, I didn't want to have to report to
anyone about how I was doing. I just wanted to deal with doing something about how I was doing, if that makes sense.
I hope you can find something useful in what I've written. I'd honestly love to know what your thoughts are.
