Love might make people a bit more foolish, but I don't believe it actually makes them stupid.

So, then, I think the risk that you or I have to take is trusting people when they decide they want to take the risk on us, even if we don't agree. Of course putting it in simpler terms does not actually make it easier, but... it's his choice. He has weighed up all he knows about you, and he has decided it is worth the risk. You, or I in your shoes, do not have to agree, or love him back yet, or even stay forever if it turns out not to serve either of you. You just have to trust him to make the decision.
