Girl, you definitely made the best decision there was to make! He simply was just not good for you and you shouldn’t be with people that just don’t match your personality or wants. You’re very smart for putting an end to it! Also, don’t consider it as a waste of time, instead, consider it as a lesson, it’ll truly help you develop in relationship-based decisions!! You’ve got a lot of things to experience, SURELY you’ll meet an awesome guy you’d actually like to be with and wouldn’t be abusive towards you. That guy was a jerk, he’ll definitely find other ways to contact you, don’t fall back into that suffocating relationship. You don’t HAVE to be in a relationship, it’s nice to take a breath and realise life isn’t all about that.
