What would you say in this situation?

he used u, which is very sad. I'm a guy so can think of how an ego works lol. I think that if u like each other u would like to see each other as much as possible. If u want to slap him in the face, I would suggest u the following: text him. "hey, mid March is coming soon, but I am now seeing a lovely guy tho. I'll try to make some time for u but don't depend on it. I don't find it useful to risk something great over u". That would touch his ego ;)

I'd just tell him, "Alright, talk to ya later." and then ignore him

Don't call. Don't text. Don't email.

Pretend you forgot about him or he isn't important (or even worse, wasn't memorable in bed!) and if he's like most other guys he'll get curious as to what you're up to. More than likely he'll eventually call, text or message you and ask if you want to get together. When he does, tell him that it sounds good but you're super busy. Blow him off that one time and then wait a couple of days. Then reply to him and tell him you want to get together and go do whatever.

Don't make any specific plans though. Just tell him you would like to hang out or "go do whatever".

That way there's no pressure as far as plans go, but he feels like he can just chill and reconnect with you. And obviously figure out why you didn't chase him around like he would have liked.

Id say well thanks but I rather you not message me after mid march bc you have a tiny...BRAIN! and I met someone better or im too good for you and I made a big mistake that night sorry to hurt you just make it seem like you're dumping him

im not gay but i'll try.

"Well. I do not think that I would like to have wine at your house anymore or have things lead to another. In fact, I have a very nice fiance that is waiting for me at this very moment. and she is FEMALE.(that should surprise him) goodbye.

p.s. you need to buy a better quality wine

hes a jerk just leave him alone and live ur life1
