ok so, i went out with this guy for like, a month. and then he broke up with me saying "we hardly knew each other." then three days later, he got back together with his ex. (which didnt last long.) since then he would flirt and stuff sometimes, but we never actually hung out again. now he has a new girlfriend, and theyve been going out for about 3 months, but the thing is, it seems like he flaunts her in my face. like he will see me walking and he will go out of his way to move in front of me. and he pops up everywhere with her. i think some of it is more than a coincidence. also, he texted me once, and poked me on facebook(while they were still going out.) and he will stare at me from far away, but when he walks by, he deliberitly turns his head to the side. one time we did hole eye contact though.
what is up with him? why wont he just stay away from me? or am i just being paranoid?

Hey girlie. I'm not sure why he does it--probably wants to make you jealous. Just ignore him and go about your own business.
