When I read this thread title my heart sank because I've been there and I know it's horrible. Well, I guess we all have, butlike youI really suffered. But the good news is that I'm over it.
Are you referring to someone you've been with for a long time, or someone you desperately want to be with but they don't want the same thing?
I've had more of the latter--2 instances of that over the past 6 years. The worst was when i separated from dh and was in love with someone I'd known for many years (platonically). I actually moved to the US in the hopes that we could be together. He'd lead me on, and then pull back and I'd not hear from him for weeks. It turned out he didn't know what he wanted. He'd just split from his wife; he was having a long distance relationship with someone else (but didn't tell me); and I just got so depressed, I mean I was practically suicidal. It just felt like pure rejection, and I even sort of hated my kids irrationally because I suspected it partly had to do with my having the "baggage" of kids.
Eventually I accepted that it was never going to happen and I moved back to England and met current dp. Now, when I think about the man I pined for, I think thank god I didn't wind up with him. He's broken lots of heart; won't commit; and is frankly a little insane.
Alsoand this supports thesadone's wise wordsI see the people he's been with and I'm shocked. I mean, really these are not attractive or nice people. It really didn't have that much to do with me after all.
expatinscotland said this great thing: "the best way to get over a man is to get under another one."
I think once you meet someone else it'll be much better. I hope you feel better soon.
