Danger ! Danger ! I am currently dealing with my ex wanting to be friends with me and it just drags everything out . Essentially you will have to break up twice ! It’s one thing to stay amicable but being friends and emotionally attached will hurt you again. If he moves on you will be hurt . If you move on, he will cloud your new relationship
You need to cut your losses and make every effort not to allow him to be your go-to unless you want to go through a second breakup -or maybe you want to try and get back together. ?
