How do you know when a guy wants you in the right reasons?

@SW-User I've had this happen to me instead he said "I really like you"..a few days later asked if he could spend the night to his house. I have bad luck with guys.

@kaisamar I'm sorry to hear that, but sadly from what women I know have told me it seems all too common. We aren't all like this but a lot of us are unfortunately. Ideally, guys would learn how to be friends first, but many just have one thing on their minds and the difficult thing for girls to work out is if their new guy is sincere or just telling them what they want to hear.
