My bf broke up w me bc he said he doesn’t love me like he used to and he wants to try new things and be single and have sex with other people since he’s never done anything with anyone else. I was his first girlfriend first kiss first time having sex etc. i keep trying to tell him we’re so good together why would he want to give that up just to see what else is out there but it’s hard to compete with a fantasy. I’m really hurt but is it normal for him to be feeling like this? He’s 18
