I have met this work colleague (let's call him Pete) for nachos and beer once about 2 months ago... he told me we should do this again.. and since he absolutely wanted to pay for the whole thing the first time.. (I wanted to pay my share).. so he said 'you pay next time' (always a good way to get a second date

)...
So the next 'date' is tomorrow.. his gf just moved in with him about 3 months ago... whenever I ask him if everything goes well with her.. he always say 'yeeeaaahhh' with some hesitation... like he's not excited.. just OK with it..
I'm not sure if he is just 'checking' if there is a possibility with me.. it's kind of 'weird'.. but I always told him that I loooove my freedom.. (hoping he will get the message)...
Today I was going to his office (Pete).. so I passed in front of this other guy's office (married guy).. and Pete was in there.. so I stopped (the door was opened).. the guy at the desk looked at me and said 'me or him?' I said 'him'... then he looked at Pete and said 'lucky bast*rd'... hummmm
I like Pete like a friend but nothing more..

I will go this time.. cause I feel I 'owe' him.. but if I feel he's into something that will be the end of our 'nachos and beer' dates..

but I have to say that, so far, he hasn't made any 'pass' at me.. I have to say that he's a true gentleman though..
