Her friend's BF(27 yo) is a totally nice guy. He spends tons of money on her and helps with everything (he even carries her bag always!). Yesterday he bought tickets for some only for girl show(quite expensive) for her and all her close girl friends and my GF was invited to join.

So she was happy to accept it and started telling how this guy is nice and caring and so on (with that kind of look, that she expects same from me). I laughed and asked if he already sold his kidney. Then i asked if he is still a virgin. She told they still didn't have sex yet (1.5 years passed!). Then i told that waiting for the bus will not work best and he should order a taxi for them. Because i'm sure that she would ask me to bring them there and back. Even it is couple miles away from me, i don't want to do that.

It was the third time she was talking about how this guy is good etc. First two times i just ignored it.

I'm thinking about what if she starts complaining like 'he buys that and you don't, he does that and you don't'. How to handle this behavior right?
