If he really did ask her to break up with you for him, you’re way better off without him! 😯 It’s a pretty cowardly thing for him to do. 😕 And it doesn’t indicate a good character or someone who’s going to be able to handle the tough things in life, directly, in the future.
But… he may know nothing about this. Don’t assume without talking to him directly that he was behind this. She may just be a drama queen and a trouble maker. So next time he calls you, talk to him about what happened and see if you can get a better idea of where things are with the two of you.
