It really shouldn't matter to you whether your ex will last with his ex that he went back to. Unless you still have feelings for him there should be no reason for this. I would suggest that you just continue on with your life and don't about what your ex is doing.
i would have to say... maybe. there are probably two reasons: he's either making you jealous... or really over you.
Your question doesn't provide enough information to provide a worthy answer -- was your ex on the rebound when he became involved with you? Are there children involved? Is there money issues with the ex? Did the ex talk about his ex all the time during your relationship? How long was your ex with you? Why was your ex an ex to begin with? How did he attempt to resolve his prior relationship difficulties prior to becoming involved with you? Was leaving his ex his choice or was your ex not given a choice by his ex?
If you don't want to get back together with your ex, then yes. You are over them.
i would sabatage the ex to win him over.
'Ex' means the relationship is over and you have answered your own question 'you're over your ex' so stand on your own two feet and nicely, but bluntly let him know you are not interested in getting back with him.
if he was your ex you should be over him. If your not over him you should tell your friend or try to get him back.
get over it already
Go back to him
get over it
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.
Simple answer: You don't, hes your EX, so get over it and move on already
Simple Answer: You don't. Your relationship is over, so get over it and move on.
You guys are not meant to be
Go with other guy. But get over the ex so that new guy doesn't feel like he's competing or being compared to ex. Ex obviously only wants what he can't have. If he gets you back, then the game is over.
