This is one of the first girls I’ve really had strong feelings for and would like to see something happen again down the road. Here are some more details. I’ve dated a lot, but not really had any long term relationships. I was in a relationship with this girl for about 3 months (my longest) and we lived together. We started as roommates and then things changed. In the end I think things just moved too fast for her and started going awry. We went through 1 month where things were really not too good and at the end of the month I made her move out. I helped her find a good place and the split went well. It’s now about 20 days later and it’s her birthday. We haven’t talked since. Should I send a quick text or not?

No

No I would not, the past is the past. Unless you want to try to be friends with her then I would.

If you just want to be friends then go for it. If you are trying to make something happen then no, it's too soon.

Sounds good and friendly to you, but how do you think she would feel at this point. Leave well enough alone, and don't bring confusion or false hope into her life. What do you think, is she over this, or not?
