Please help me..thanksHow to get your ex back..please help!?
You need to sit down and discuss this with him. But now you are stepping on another girls toes and that is wrong. I would wait to see if he breaks up with her on his own before talking to him about your feelings. After all, you wouldn't want to be the reason he dumps someone else and you don't ever want him to wonder later down the road what may have happened if he would have stayed with the other girl. Just b/c you were together for 4yrs. doesn't mean he is yours to walk in and steal him back whenever you feel like it. He has moved on and it has been 3 months since you've broke up. You have to let him decide whether he wants to be with the other girl or not. If they break up then you can seize the opportunity, otherwise he is off limits to you.
