<human>: Can you provide a brief overview of the text?

She and I were good friends for a while and one day we decided to become intimate with one another.  We became more close, but it was more of just for sex and not a real relationship per say.

Well a few weeks ago she met a guy and they're now dating and I'm happy for her and we still hangout and talk a lot. The problem is we're still very close?  Like I'll spend the night with her cuddling or just talking, but no intercourse. Sometimes she'll grab my butt in a playful manner not really lustful and I'm not really sure what to think of it.

A few days ago I spent the night with her and she lied to her boyfriend and said I went home when I didn't so I don't really know if this is appropriate or wrong and I just need some advice.
<bot>: Me and my best friend had sex a number of times and now she has a boyfriend and is still very playful with me.
