I don’t want my gf to talk to other guys or add on snapchat / giving her number.

She has done it before and i got mad, she accepted it and deleted the guys.

And I don’t know if I want this, we love eachother but i am toxic for her. She can’t talk to other guys when she is with me and no I’m not willing to change because it’s the same the other way around, but should I end the relationship? Even though we love eachother?
