advice on still being attached to my ex
i broke up with my girlfriend around 4 3 weeks now and we didnt have any contact at all till a few days ago and i found out that shes interested in someone else and it really did hurt but at the same time i still feel attached and kind of responsible for her? like i still wanna take care of her as much as i can and i just dont know if this is healthy or not or like being friends with an ex is a good idea in the first place?
