I dated my ex for over a year and it was the best year I have ever had. I have never been that comfortable or close to a girl before and I know she felt the same way. Everything was going great until about three weeks ago. She started hanging out with her new friends and doing different things that she wouldn't normally do like drink and party and stuff. I freaked out and told her I felt replaced and it all went down hill from there. I think she still loves me and cares about me but I haven't talked to her in about a week. How do I know if she has moved on or is trying to move on or if she is just waiting for me to make things right again?

Why don't you just try to make them right again ? I know that rejection is a very big deal in teens, but sometimes its needed and that's reallly the best way for you to find out. Let her tell you how she feels, stay calm with her, try to prevent arguments and there just might be hope. Apologize for what you may have done, IN PERSON. I waited on my ex to do it in person and it didn't happen so I moved along, maybe she just wants that ? I know so little about the situation. I'm just throwing out some ideas. Don't make yourself look like your begging for her back, just ask if there's anyway you could talk about it, or anything you could do to get things back to the way they were.Just because she's got new friends doesn't mean your replaced. Although the partying is very bad for her, you should encorage her not to do it, but not make a huuuuge deal of it. I wish you the best of luckk (:

If you want her back, then you have to let her know. But it doesn't mean that she will take you back.

If she hasn't contact you all this time, then chances are, she's slowly moving on with her life. If she wanted you back, she wouldn't leave you hanging and wondering.

Its been a week, call her, and find out. Just be prepared for anything, and everything!
