Shit, that sucks. At least you found out before you ended up getting seriously hurt. He's without. You'll find someone else.
That most definitely sucks, but Danieyeli is right in that you'll find someone else, and thank your lucky stars you didn't find out later on down the road when ya got serious.
I am sorry that has happened to you...! that is most defentily not fun at all.! I havd that same thing before I meet my boyfrend.. there was this boy at work. we flirted all the time and I ended up liking him lots and he ended up not likeing me at all.. so I know how that is..l. but I am a strong believer that there is someone foreverone. one day you day will come and you will find the perfect person for you..
