difficulty moving on?

Like the first 2 people said, you could be getting a big jealous. I know when My relationship ended i cried, then didn't really worry. But the minute he found a new girl I felt sick to my stomach daily. The trick was having fun and meeting new girls. My father used to tell me "don't cry over someone who won't cry for you" sorry to say it a big harshly but it's obvious she's not meant to be in your future. Your young anyway:)

This is kind if difficult when it comes to a guy still hung up over a girl. My guess is sometimes people get into a new relationship right after their last break up to either get over their last one, to move on ECT. Maybe go out and meet new girls. Any buddies of yours have any friends that are girls? Maybe your stuck because in a way she's moved on before you have and you aren't sure what to do next. Just wait for a better opportunity to gone along.

Everybody deals with breakups in a different way. She seems to be handling it her own way, and although it is perfectly normal for you to be curious about how she is doing, try to concentrate on yourself and maybe find some more distance from her. Do things that make you happy, maybe there are a few things you neglected while you were in the relationship. There's some great information that could help you on http://www.thebreakupwebsite.com/ hope this helps you!

Wow seems like she never liked or loved you bc if she did she wouldve never moved on so quick unless shes trying to get you jealous but other than that you need to get over her i know its hard bc i been through it before with my bf we been dating for 3 and a half yrs and we had the same situation you and ur ex had except i didnt move on and he didnt either. But i tried so hard to get over him and i couldnt. But hey im still with him we got bak together so maybe you and her will get bak with eachother if it was meant to be but you can wait forever bc if you wait for her shes going to take advantage of you! just talk to other girls that will help alot trust me.But go out have fun try forgetting about her bc i know its gonna hurt you if you were to see them together but whatever you do dont show her ur feelings bc she will step all over you just take a deep breathe and walk away. Just be strong you ill find someone better trust me :)

Maybe you are a little jealous and it makes you upset that she got a new boyfriend its normal to be a little jealous, but you will move on soon
