This guy

It’s taking me a while to get over a guy I was casually having something on with at work. And the reason why I’m mentioning getting over him is because I so happened to notice that he was texting and flirting with a new girl.

I called him out on it and he denied it said they know each other from their previous company.

Long story short I don’t believe him- hence the getting over him.

Today I walked up the stairs and he happened to walk their too and he touched my bum.

I really think he wants he’s cake and eat it too by having two girls and whomever else he is flirting with...

Today I also realized I’m not over him and enjoyed it when he touched my bum. I need to know how to handle this situation...

I know I don’t want him but yet struggling with getting over him
