Why are more men going towards me?

I've been pretty upset with my boyfriend lately for various and really good reasons. I don't like drama and get mad because it's sunny outside.. Anyways it's making me sort of withdraw.. I don't like the criticism and finding odd things like messages from girls on facebook and such... Anyways to my point... I feel all of a sudden more men are hitting on me...they weren't as much as before... why???
