getting over an ex

Ladies I need some good ole advice please. I've been doing so well getting over my ex, I've been dating and hooking up and have been living it up! But lately now that he's back in town I haven't stopped thinking about him and it's upsetting me so much. 😔 I know how strong I am and I don't want to let some little boy mess with my emotions when he isn't even caring. Any advice would be wonderful.  💗
