I started dating my ex for some reason and I thought it would be different but he doesn’t make me happy he’s never made me laugh or talked about random things with me. All he does his hug on me and kiss on me and it’s boring I’ve talked to him about it but he hasn’t changed He just doesn’t make me happy we aren’t even going to the same high school and I don’t want to waste my time on a pointless relationship he keeps texting me but I haven’t answered I have him in 4 of my classes I broke up with him on Friday and Monday is going to be awkward. What do I say and how should I say it.

These are the texts he has sent me what do I do??
