you have to either dump your bf or u cheat
become mates
I would suggest you let your ex know so she can choose who shee wants to be with. If her relationship at the moment is serious and she is happy, i suggest you do not get invovled and move on. There are plenty of females out there.
You cannot know what your ex actually intends to do. What you can do is act in the way that best serves your own needs. If you want to put the relationship back together then you should act as if your ex is serious about wanting you back. Your ex may change his/her mind even if that was not their original intention. On the other hand, if you do not want the relationship to continue then act so as to end it now.
Only you and him know what went on in your relationship and why it ended.
It sounds like you should have a conversation with her about how she feels. You need to know how serious she is about you and the possibility of a relationship, and where exactly she stands with her ex.
'Ex' means there is no longer a relationship and since he does have a new relationship then you should stay out of his life and move on with yours.
There is a good possibly your ex may want to get back into a relationship with you again. Be wise and think about it before leaping into another relationship with your ex. Tell your ex you will think about it; do so and then let them know your answer.
of course. he will always probably like you in some way if you had a serious relationship before.
It is time to move on and look for someone else. A so called "open relationship" is not the answer to forming a stable relationship. You are too young to get too serious with anyone. Aim for a friendship with a few mates rather than a serious relationship with a single boy..
dont just dump him
just talk to her about it and hopes she wants to get back together
try talking to her. It depends on what happened though... if you were serious she may very well want you back. Dont give up on love!
