Question!!

So, I recently met this guy and we've been on a good handful of dates, and he's so sweet and respectful. He hasn't pushed me to do anything and is so uplifting and encouraging of my personal life. The only thing is I'm 21, and he's 33, and he has a daughter who's 12. Is that weird? I really like him and we seem to really connect and I always have such a fun time when I'm with him. I don't have a lot of friends outside work and a few of them think it's really weird but a few say I should go for it if I'm happy, so I need some opinions! Is this something I should keep going?!
