Advice on fling

Ive been divorced for almost 2 years and had a fling with a guy for 6 months just hang out and sex I cut him off because his friend told me he was looking on dating sites and I suspected he was having sex with someone else because of his sex drive when we would see each other, so I cut him off.

Now I want to call him to have sex only 😞

Have you guys been through this before.?

Would I look dumb if I did hit him up for that.?

*I have needs 😫
