HELP!

Ok sooo there was this guy I really liked for a while. I thought he liked me too, but I got scared and slowly backed off and (here’s the sad part) * I feel like since I got scared and backed off I watched him lose interest in me*.... but he got back with his ex (they have had a weird long on and off relationship)... she hurt him bad last time and I’m just SAD and need reassurance. This is a total Taylor Swift “You Belong With Me” moment 😭
