Sex with my ex-good idea or not??

We were together for 5 years and broke up a month ago. We had broken up perviously, for a month, and I found out after we got back together/decided to work things out that a week after we broke up he went to the club and made out with some random girl. Lied to me about it the whole time we were working things out. After 5 years, a week? Really?! It hurt to be "cheated" on and lied to, and Im too good for that. I know I deserve better. I kicked him out of our shared apartment and have not spoken to him since. I do not have any plan to get back together; I despise him for what he did to me after so long together. Problem is- I am pretty "frustrated" at this point after a month. I really desire to have sex with him again, no strings attatched. To relieve my frustrations and show him what hotness he is really missing out on. BUT, I dont want to be the one to initiate this after he screwed me over like that!! For all I know he could be screwing the girl he met at the club back then, who knows. I doubt it, but its possible...? Maybe he has moved on? Maybe he is sitting home as frustrated as I am but doesnt want to ask/bother me after what he did? I cant stand him or our past relationship but I want sex!! And dont want to do it with a random guy even if I am in college and Im sure there are plenty around. Ugh!!! What do I do?!!?!

Sorry to say but ur lieing to yourself. Dont mean to sound harsh. If you dispised him that much you wouldnt even consider it. Your fooling yourself. Love has no boundaries. and hurt is even worse.
