Thanks for everyones input. Its cleared a few things up for me, but i'm still a little confused.
What does you think A meant when he said to my friend "No the opposite" when she asked him if he was chatting me up?
I also saw S again yesterday and he still wasn't looking very happy so i asked him if he was ok and he said 'yeah' in a real grumpy voice. so i said "well your obviously not, tell me whats wrong" He just said "im just still really mad at A, i can't believe he'd do something like that" so i said "i thought everything was OK between the 2 of you now" and he just shook his head.
My initial opinion about what happened that night is that, A didnt like me and he was messing around, thats why i tried to cover my back when he asked for my number by saying "yeah i'd give you my number, i give my number to anyone"
I thought he was asking me out for a drink either to
1) see what id say and if i said yes saying "i was only joking" to make me look stupid or
2) he was trying to get my number and would then give it to S so he could text/ring me
But because they've been arguing for the past few days, its made me think and im not really sure whats going on. Maybe A really does like me, thats why S has got so upset because maybe he sees it as a "betrayal".
Most people who read this will think "ohh A's a bad friend because he knows that S likes you" but looking back on everything, it may not be the ideal situation but to me it seems as though A has made sure (numerous times) that im not interested in S and now that hes sure that nothing would ever happen between me and S (hes been asking me out for the past 2 years and ive always said no, i thought he'd have got the picture by now) hes decided to make a now.
I dont really know if that makes him a bad friend or not. Maybe you guys can help me
Sorry about the length of it again
