Advice ?

I’m starting to date again (college student) it’s this guy he’s so sweet and honest but he’s a little on the heavy side ( I like them thick anyway) I’m 19 and for my age I’ve found out what I want from relationships. He’s successful and humble but I’m afraid because I feel like I have nothing to offer.

So I guess where I’m getting at is :

Am I enough for him ?

What if his size bothers me?

And what if I’m afraid to trust him because of my past relationships?

(Please be polite!)
