Why would a guy you've known for years start acting different around you?

Anonymous

I have a friend that I've known for nearly 16 years. We've always been fairly close and able to talk about anything and everything.

A handful of years ago I went to see him and he acted really different. Rubbed my thigh, slapped my butt, complimented everything from my hair to my accessories, hugged me from behind, made passes that others noticed and commented on, and I woke up to him rubbing my arm. One night I went to the couch in the middle of the night and the next morning he asked why I slept there and said he "kinda thought I'd sleep in his bed with him."

He even asked me to an event with him and we had a lot of fun. I tried bringing it up and he got a bit weird about it, said we're friends, and we just acted like it never happened. We're still close, and he tells me I can confide in him and that he understands me.

I'm just confused. Why would he suddenly start being this way? I'm honestly not sure what I think, I guess I've never really thought about it until that point. Is this just being friendly or what's up with this?

I decided to apologize for my flirting. While I realize I only did so because of the way he acted, I also know I was in a bad headspace. I was just out of an abusive relationship and wasn't thinking clearly. I reached out and told him I was sorry for the way I acted during that trip, and that I feel like that trip was when we became less close. I said I felt like the whole trip was just off. He responded and said it probably did affect it, but that it's in the past. I don't know what to think.
