You're an adult now so who you date is your prerogative. Just stay smart and always look at your relationship with open eyes and not rose-colored glasses. If he starts trying to control you, it's time to leave and don't look back.
I was 21 when I started dating my (then) 42 yr old ex. We were together for six years, lived together and genrally did very well. In the end we broke up as we were two different people. The point is age doesn't matter and the reasons we broke up was the same as many same age couples, so long as you are happy that is all that matters. You are both adults and as such can make your own decisions; life is too short at the end of the day. Enjoy yourself and just treat it like u would any other healthy relationships xx
As the mother of a 19 year old girl I think I would find the age difference difficult to come to terms with. I just can't imagine what a 30+ man would have in common with her. I know that's a silly thing to say as everyone is different. I would wonder how long it could last and the likelihood of it being a 'success'. As two adults you have to make your own decisions but these of my views as a mum.
