How can I keep my emotions in check?

Before now, I never cared much in relationships or I'd say I try to maintain a steady momentum. But these days, I tend to set my emotions lose when I fall in love. I love hopelessly but not stupidly. Suffice to say this has hurt me real bad in recent times. I recently got out of a triangular relationship. It sapped me emotionally and I'm still trying to get over it.

I'm not the instant ladies man but when they get close, they seem to fall for me and I'm unsure of what to make of it. I have too many ladies around me and trying not to hurt them. Currently, there's one cozying up to me. The feeling is mutual but I feel it's too early to enter into another relationship and I'm planning on relocating soon.

Honestly, I spend a lot of time thinking about this. I have a steady job and doing quite fine; I'm in my late 20s too.

Is there a way to shelve these emotions and stop these girls from coming too close?

Mods, kindly retain this thread here in the family section. I don't appreciate the juvenile comments of the Romance section.

Thanks
