Weird or am I too naive!

A girl visited our office from another office, she was young I mean about 22/23. A single guy from my team was interested in her... Which is fine. Invited all of us 2 dinner in eve. So we were like 4 girls n 5 guys hanging out after office.

During dinner we found out she was married... But she kept on constantly complaining about her hubby.

I decided to leave early about 9pm.

Next day I got this info from my team mate guy (he is a close friend too). That after I left another guy from our team took her home and had sex (he has a gf, she was away on work). That was a shocker. So my team friend is pissed off.

Now a day later team friend meets her again for dinner and they get close!

I was like what the hell! This girl is married n already slept with another guy in the team n you want to be with her. He is like I am single and I like her... It's her decision.

I was his good friend till date, but after this episode don't feel like hanging out with too much. He has no principles...
