Cant let my ex go

Every time i talk to him i cry. I miss him so much but he’s so shitty to me. He always talks about how other girls will have sex with him because i didnt and it makes me so sad i had sex with him twice and it just hurts i wanted to wait but he had other plans so he broke up with me. I hate this feel. I feel like i have no one to talk to about it so i just cry and cry. I wish i could start over and not ever had met him. He wasted 3 years of my life. Now he keeps talking to me about some girl he’s talking to. I forced him to block me because its for the best. I wont call him back to back or text him because im blocked so yep. Now my throat hurts
