He Gives Me Anything I Want, Calls Me Frequently But Has Never Asked Me Out, She Needs Your Advice

There is this guy that is very close to me, he calls me often, but has never asked me out.

I don't know his house, he doesn't know mine, he has never taken me out on a date but does more than enough for me.

What should I do? Because other suitors are coming and I like him.
