I broke up with my boyfriend he told me if we fought again we’d break up I realized the I felt I was selfish for holding him back from moving on and i was so dependent on him was it wrong of me?

No i was not your fault these thing happen it also depends on what happened while you two were together

You made a powerful decision. To have threat of breakup hovoring isn't healthy. Better that you ended on your terms then wait around for him to end the relationship. It was going to end, you just had the strength and maturity to verbalize it. Strange as it sounds, sometimes being the initiator of breakup is more painful than being "dumped". For the very reason you ask... You question if you made the right choice. You did. Be sure of this. You will find someone who is better suited, you respect more down the road. If this guy was so great, you would not have fought as much in the first place. Constant fighting shows a lack of respect from both of you. So it wasn't meant to be and you can't meet Mr right if your spending all your time with me right now!
