I think the reason some girls go back to a guy when they do this is because they feel they do still love the guy. The best thing to do is pull yourself up by your boot straps and move on.
When he is back and you still love him then why asking the question. Simply go and enjoy.......
Apologize to him. Plus, break up with the new guy.
To get the attention of a guy that you love but he doesn't love you back would be to talk about some things that he likes just to get you started.
Be there for him when he is sad, still show that you care for him, it doesnt always work, but that can get into a guy's heart answer:
(coming from a guy) if you still love them tell them. if they are shy or afraid of commitment talk with them about that.put yourself in their shoes
the guy tells you
Yes, you can be in love with a guy and still be in love with another one. It isn't uncommon to love two people at a time but it may cause problems in both of the relationships.
You get over it and move on.
Forget him
FIRST, find out the reason that why he broke up with you. NEXT, if both of you still love each other then maybe you should get back together.
It appears this guy is extremely immature and not ready for any type of commitment. When you love someone you just don't dump them, but still want them. Tell this guy to hit the bricks!
