forget about both of them
I would tell my friend to be cautious about going out with my ex.
I honestly wouldn't do it, dating or going on a date with a friend's ex is a terrible thing to do, it's like a subconscious sort of friend-code where we don't date or do anything with a friend's ex.
Chances are, he/she is.
we'll the good thing is to tell your best friend and see how he/she goes with it
Just be happy for her =] Your friend has found someone who loves her.
Why do you want to do anything? You said this is your EX.
I'm going to cut you.
It seems your ex boyfriend may not be sure if you want him to go to North Carolina with you and he is possibly discussing his fears with your friend. It is doubtful that there is anything going on with your ex boyfriend and your friend. Communication is extremely important throughout anyone's life so talk to your friend about how you feel regarding seeing your ex boyfriend. Be careful because it sounds like your ex just considers your friend a friend and nothing more.
Do nothing about your best friend going after her ex because she will not listen to your advice anyway as I am sure you have come to realize. Life is about learning and she will have to learn the hard way and this problem will pass in time.
just tell your best friend that you really like him and see what she says about it.
That depends on if it bothers you or not? If it does tell your friend. If she is a true friend then she'll respect your wishes and will stop seeing him.
If they date, you will just need to let things run their course. Since you gave your blessing, you can't be mad at your friend or the ex.
