After a 4 month separation from my ex who i still have feelings for, I ran into her couple of times. She definitely hates me cuz she deleted me then blocked me on fb. I kept my distance and dated other girls but i want her back. I saw her with her friends outside a club once and i actually walked up to their group smiled and said hi to every1 also introduce myself to the ones i didn't no and left. Today at university when i saw her i stood tall with a smile and said hi and she is like hi im late which she was actually, but she was all awkward. Long story short , im gonna run into her probably a lot at university and i really dont no what i should do when i see her? also im having coffee with a girl i went on a date and hooked up with at university, do u think it would be a bad idea if my ex sees it ?
