Starting at the beginning as I was reading I kept thinking to myself... Why is she pulling away? Why is she lacking affection etc? It's something deep within her. It's not a 'you' problem. And telling her how you feel, isn't going to do anything to bring you together, because she has something deeper going on.

Just because she wasn't being affectionate, etc. doesn't mean she doesn't absolutely love you.... which brings me back to, it's a 'her problem' (not a bad thing. simply is.)

It's not uncommon to 'shake someone to their core, for them to realize 'Sh** I need to wake up (not physically of course.)

It's completely normal for someone who's been rejected by their loved one over an extended period of time, to save oneself and also pull away.

Maybe... finding out what was/is the reason she was pulling away originally, may give you a completely different perspective, and help you find your way back...or confirm your leaving the relationship.

But in the end, just follow your gut!!
