not clear...

in the end the guy i met for lunch has a BF for already 2 months...i don't get it yet, he invited me to lunch, all the people around me said that there was tension between us (like in sexual tension), the first thing he asked was if i was already single and dating and when i answered i was he said "i've been seeing a guy for the last 2 months, he is really nice"...WTF??? whatever, if someone is supposed to come will come.
