damn.... sucks for both of you guys. I hate to say the old..."Well, if you were really in love with each other..." You may look into some couples therapy for that. Not doubting you at all, maybe a bad choice of words, but I do think she may have issues she needs...."Fixed" so to speak. I doubt she does'nt love you when she says "Don't tocuh me.". She's just "troubled".
I also don't know ANYTHING about her or you so this info might be way off base. Just saying that her "problem" may have a solution if worked on. If you guys work on it. I'm sure it's deeper than that as well. Either way, it sucks. good luck.
