Is he seeing someone else?

I was recently introduced to someone trough mutual friends. He asked me out on a date but he has this womanizer fame. I am still hurt by my last break up and don't want to fall for the wrong person again. We aren't even dating yet so it would be weird just to ask him out of nowhere if he is dating someone else, but I don't want to get involved if he is.
So is he seeing someone else right now?

There is Sun in 7th house in aspect to Pluto but its separating?

You're symbolized by Mars, he's symbolized by Venus. Venus looks pretty unattached right now. But I wouldn't see you two as forming a strong bond, either. Maybe just enjoy the date as a fun experience, and take it slow if you plan to see one another again. Obviously, if he is a womanizer, being unattached now doesn't mean he'll stay that way.
