is it wrong to date someone you don't think you'll marry?

It's not necessarily "wrong". But my opinion is that if you two continue to get closer and closer, it will only be harder to go back to just friends later. You don't want to end up in an unhappy marriage, but you also don't want to be extremely hurt over the breakup. I would say that if you're both ok with it, going back to friends sooner rather than later is the best thing to do. Then you can stay in each others' lives and can find matches who you could see yourself marrying.

I don't think it's wrong. You're young, you shouldn't be looking for a relationship that ends in marriage yet. You should just be having fun, doing what makes you happy right now. And if he makes you happy right now, be with him. However, if he feels differently than you do, and he feels like you two could be married one day, you might want to talk to him about both of your intentions in the relationship. Ask him where he thinks you two are going. Tell him how you feel, and maybe you guys can still stick together for the time being.
