yes, it's possible, but don't get your hopes up too high. It all depends on how you broke up, why and what your mistakes were. If you cheated, you probably won't ever get him back and if you do the trust will be gone. It depends on who his new girlfriend is... does it seem like he really loves her? Or are they always just kissing and "doing stuff" if so, he's probably just using her and there's a big chance you guys can get back together.
but as i said.. dont get your hopes up too high, you might end up just getting super hurt and depressed
You guys are not meant to be
get a new girlfriend or boyfriend
It means he hopes that you will get back together, and that he is willing to get back together.
get over it
If he has a girlfriend, don't go back. He will do the exact same thing to you, that he will have to do to his current girlfriend. Good Luck!
It sure sounds like time to move on, but this is just a personal opinion.
If the boyfriend or girlfriend hold you back from your purpose.
You do absolutely nothing about your ex boyfriend considering he has a new girlfriend. If he loved you he would break up with his girlfriend and since he has not then he wants to be with her and you need to accept that. Just because you have broken up with your boyfriend it doesn't mean you can just step back into your ex boyfriend's life.
If you are indeed keen on getting your ex girlfriend back, even if her ex boyfriend want her back, what you can do to make sure that he will choose you is make her see your best foot forward. Show her how better you are over her ex, how happy you can become if she decided to come back to you and how things will be better now.
maybe he wants you back.
You should not. Just face it. you need to move on.
Simple Answer: You don't.
