Search Results: dating multiple people at a time

I have a crush on a guy I once knew in high school. He moved away to another country and we have kept in touch via Facebook once in a while. I finally told him I had feelings for him through a facebook message.. but he didn't respond for months. So I moved on and started dating someone else. My crush messages me 5 months later saying he got my message and wants to talk.. he called me long distance and we talked.. he invited me to come visit him multiple times said I should keep in contact with his friend that still lives where I live. He also said he had feelings for me too in highschool. He didn't like the girls where he is living and wants a relationship just hasn't found the right person. ... I told him that I was in a relationship and things got weird. He then ended the conversation saying bye sweetie keep in touch. He then posted a status saying "fuck that bitch" then deleting me... and the rest of his entire facebook friends..

I was so angry I messaged him asking why he was acting like this and I would never give him another chance to ignore me and treat me like this... No response. It's been 15 months and he just sent me a message saying "I didn't delete you because you did anything wrong, I just simply disabled my facebook... don't take it personal" ... All I said was ok hope your doing well and he didn't try to keep the conversation going... I asked him if he was just now getting my message from last year and he said he said "yes I'm on and off on facebook" ... why is he acting like this? What do I do..
