<human>: When we first started dating, everything was great, but every so often she would get stressed and/or her anxiety issues would overwhelm her and she'd shove me away, leading to us going on breaks from each other 4 times over a 2 year period. 

Recently the anxiety issues have significantly worsened, and we have barely had any contact for nearly 4 months, sex is completely out the window as she fears physical contact, staying at my house, or people being in her house. It's been weighing on me heavily and it just doesn't feel like a relationship anymore, so today I finally told her I just couldn't do it anymore and needed a break or time to myself to think and sort things out.

I feel like the biggest ass ever as she is going to therapy and trying to sort things out, but there's just no end in sight and I don't know how long I can keep doing this, as it's stressful and straining me a lot. I feel incredibly selfish, because when it's working with us, it's the happiest I've ever been in my life, but I want so much more and I have no idea what's next with her, if she can fix it, or if I'm going to be dealing with this for the rest of my life. What do I do guys?

Could you distill the essence of the text into 1-3 sentences?
