Need Advice!!!

Okay so I just got out of a 10 month relationship with my first love. He was a really great guy until the end of our relationship. I have been single for about 3 months now. This guy likes me, he's honestly the sweetest guy I've ever met. He never fails to make me happy. There's one problem (please don't judge!!!!) he's kinda ugly & a little on the big side. I know looks shouldn't matter but they kinda do to me, he would be a downgrade on looks but an upgrade on attitude and kindness. I was at a baseball game tonight and he picked me up and we went out to eat. I really need to know what to do.
