Is it a bad idea to hook up w my ex who cheated on my a year ago?

me: F20 Ex: M22

We broke up a little over a year ago. He cheated on me (slept w a different girl almost 2 years in), i gave him a second chance, he slept with someone else again.. we broke up tried again after a month and he just texted other girls.

So after that I was done and we never really talked again. He’ll occasionally text me some long message about how he misses me, and how he regrets everything he did, and how he realized i was the one yada yada. Just BS basically.

I think he just wants to know he can get me back if he wanted to. Know that i still want to be with him (which i dont). So the thing is I haven’t slept with anyone since we broke up… like at all. I talked to a guy a couple months ago but he was sorta a fuck boy so we never actually went on more than one date (not a first time wonder, sorry) And i really don’t want to sleep around with a random or be a slut.. n overall i’m comfortable with my ex.

Would it be bad to ask him if he’d want to hook up? I’m almost positive he’d say yes and then it’s only about boundaries, and making sure we’ve both been tested (std) recently.

SORTA TMI:

I only worry that psychologically he’ll think he won, by “getting me back” but i really just want to get dicked down with someone i’m comfortable with. Like sexual dysfunction is a fr thing i’ve never been more pissy n horny all at once. and ik this is tmi but masterbation does NOT work or help the feeling i need person to person contact or something.

Idk.

What would you do? This is actually just John Quiñones and you’re on TV .. but like actually

TLDR: If after a year - your ex that you cheated on a bunch during the relationship reached out to you to hook up and that’s it - after telling you for months she wants nothing to do with you.. what would you think? what would you do? Would you think you “won?”

Thank you so much! Sincerely, To much information i’m so sorry
