Hello and welcome to Psych Central!

I can understand why you'd respond to such a loving and caring man. But, as you say, he is too old for you and you don't even think he likes you. Do you think God would approve of such a relationship?
Instead, I suggest you ask God to help you find a young, loving man closer to your age. And seek out loving and caring women for right now, who can give you what you seek.
I am going to recommend that your post be put in the Relationships Forum, so you can get more responses.
Again, welcome. We're glad you're here.
