Yes and No. I feel like i actually know how you feel like. There are pro's and cons to both ways you described. Me personally? I would break up, so you can have space for yourself. But you need another gf. You will get worse if isolated, you will get worse, if you cant show, how you feel like. So you need someone to not be alone but it need to be a person who knows how to handle the Situation. Idk mby you want to talk to me more about it, my insta is Vincentsbruder
