Dissappointing

My bf broke up with me about 5 months ago now.....It's been one of the worst heartbreaks I have ever survived. He dumped me on my birthday......He sometimes seems like he doesn't show care in his behavior but his Aspergers sometimes gets in the way with our communication....I loved him so much when we were together and after he moved and I experienced feelings of abandonment I realized it would be better if we temporarily broke up with the thought after he figured out some things that we'd be much better and we were on the same page....boy was I wrong....he never told me this but I believe through some things he's said and his actions that he believed that we weren't right for one another. Now after he's talked me into staying friends I overhear a woman in his place and he didn't deny he's interested in her. Now I cannot deny that we will never be the same to one another. He's hurt me by his less than straightforward behavior and words and I have to admit that my trust in the opposite sex has been injured.
