the last thing he told me was "call me" . I haven't text him yet and I haven't called him... what can I do to gain his intrest
I don't know you and would not presume to judge you.
But I'm pretty sure you'll just be messing up more if you keep thinking along the lines of "manipulating him" and "making him" like you.
Play it straight. Be yourself.
He will either like you or he won't. You have no control over that. You have no idea what influences he's living under. And that works vice versa.
Honest dialog will bring you closer, I think.
