If a guy sticks around after a one night stand?

Anonymous
I had a one night stand around 5 months ago but ever since we've been keeping in touch. We text a lot, hang out sometimes (not too often because of his work) and well we do still have sex. When we are together, even if in public, we act like a couple, kiss, hold hands, hug.
I read many stories of guys disappearing after sex. Especially ONS.

Why did my guy stick around for so long?
