My heart aches for you Nuu. Gotta say that I had a similar experience this time last year. I met a really nice guy and was quite smitten with him. We dated for about 3 months and he broke it off. Said he needed to work on himself. He suffered from ptsd from Vietnam . I thought I had done something wrong. I questioned myself and wondered how I had screwed up. It took me a while to realize that I hadn't done anything wrong. It just wasn't meant to be...and it's ok. You can move on from this also. The right person will cross your path when the time is right.
