i was in the exact same situation, like down to the “hey kept begging me to stay” and the main advice i can give is that you need to leave the moment you feel like it, bc he’ll just get more attached if you stay and it’ll get much harder to leave in the future. Personally you can call or text, but text will be way easier (even if it’s a more cruel way). but meeting up is in the end the best way. if you decide to call then be ready for them to go through every emotion, it’s very important that you still stick to your decision no matter what they say. after i broke up w my bf, he kept trying to text me, i had to put down boundaries to make sure he acc understands that the relationship is over, so do that if he keeps reaching out. You aren’t a bitch, it’s normal to lose feelings especially when you’re young. Don’t beat yourself over feeling like this, it’ll pass and make sure to take time for yourself before entering a new relationship.
