<human>: This guy and I have been seriously talking, going on dates, and have all-around been acting like a couple for almost three months now.

He always reassures me that he's not just in it for sex, but that he actually does want to be in a relationship with me. But every time I bring up making us officially in a relationship, he dodges the question and just says that he's afraid of me, more specifically, afraid of falling for me.

His last serious relationship was about a year ago and he was cheated on, so I understand his hesitance, but it's really taking a toll on me. I don't want to continue pushing the issue but at the same time I can't bear feeling like he's somehow ashamed of me or that he doesn't want to lose the freedom of being able to sleep around.

Any opinions or suggestions will help.
