Back story that prompted this question... so my friend told me about a girl he likes that he also found out (after making out with her) that she has a bf. Ok, yeah she was drunk at the time but still... the girl not only made out with him that night, but another guy. Her coworkers had to remind her that she had a bf when she was making out with my friend.
I don't know this girl, but I wonder if she's leading my friend on? He's apparently known her for awhile but she's never once mentioned a bf. She even asked him if she could stay over at his place at the beginning of the night. Maybe she just started seeing her bf and they're not serious yet?
Is it normal for girls (and guys) to not mention they have a bf ever? Because I hear stories like this a lot... the person doesn't find out that the other has a significant other until things have gone too far and feelings have developed and all that.
