Is he only seeing me for a dollar sign?

I'm a 21 year old female and I'm somewhat "friendly" again with a used to be FWB who is also 21. We were screaming around when we were like 19 and didn't want anything serious, he was freshly out of a relationship and I was a mess who didn't know what she wanted. We still went on dates, I met his family and he met mine. We screwed around for a few months and just eventually stopped. Not sure why actually...Anyway....His parents are filthy rich and both of us hold VERY high standards which I'm not upset over. In that aspect we'd be perfect for each other. We both love the luxury things in life and have the mottos "if you can afford it, why not?"

I've met his family, they seemed to be a fan of me. But every time we've made small talk (even now) he keeps asking... you're still studying to be a doctor right? Which the answer is yes. He's always asking me about school and how much time I have left. He's now asking me to hang out.. I have nothing against it we haven't talked about sex, relationships or anything of that nature. It's strictly been what are you doing with yourself now and what are your plans for the future?

What exactly does this mean? Am I being seen as jus a dollar sign or someone who he probably has his eyes on?
