Can Muslims date non-Muslims?

I’m wondering if anyone has any experience with this. I’m sure it probably depends on how conservative or liberal the Muslim is, but what are your thoughts on this?

I ask because I’m a Christian woman currently interested in a Muslim man. He is from the Middle East and we met in the US.

It also might be important to know that his father is married to multiple women. Does this mean he probably plans on following suit?

As we get to know each other better, I’m sure these conversations will come up between us… But I just thought I’d tap the collective quick. :)
