Contact with Stepdaughter's Boyfriend

I'm online window shopping for daily deals and got distracted again. (I'm easily distracted apparently.) My stepdaughter's boyfriend emailed through facebook and I got distracted.

My stepdaughter's boyfriend is on both mine and hubby's facebook pages now.  We saw some pretty pictures of my stepdaughter on his page and he's cool with our contact which is a nice change.  He also really appears to care about her so that is nice to see. 

She needs a regular healthy relationship with the opposite sex so I was hoping that was what he would be for her.  I really don't know for sure since we only met him once.
