Hello. 
My boyfriend broke up with me a month ago. We had been dating a little over a year. We started out the way every couple should. We met online...emailed for two months before our first date. We had marathon phone conversations and opened up to each other about everything. By the time our first date came, we were already so comfortable with each other. We had a great relationship. We traveled together, shared the same sense of humor, spent time with each other's friends and families, and got to be so close and comfortable. I was in love and convinced that I would marry him. (and that's a huge step for me) 
His reason for the break up was that we "didn't fit perfectly" whatever that means.  
After we broke up, he told me he had a girlfriend (after a week and a half!) Now, the sensible part of me thinks that this reeks of a rebound. Surely, after taking time like we did to get into a long relationship and knowing each other so well, he can't just have a new girlfriend and share the same feelings for her. Or, he knew her before we broke up and was finally free to date her. I convince myself that this won't last with her because he is pushing for intimacy so soon with her. I know guys are problem solvers. If they aren't getting sex, they find a way to. I just hurt more than I thought possible, and while he is spending time with this new girl, I am miserable...and it's Christmas. How can he move on so quickly? How can he be with another girl and not think of all the memories he and I shared? Doesn't he hurt like I do? 
I don't know what I'm looking for. Validation maybe. Someone to tell me what I'm thinking about this situation is right. I can't even think of dating anyone else right now. I can't downshift that fast and we shared so much, I can't imagine getting close to anyone else any time soon. Any thoughts would be appreciated. Thanks.
