lake Advice on age difference in dating (27 years)?

I am an 18 yr old female college student who just started seeing a 45 year old guy. He is divorced and has 2 kids who are 4 and 7. I know it is impractical because of age but is it impossible? I like him a lot and I know he feels the same way. He is a great person and a great father. I was wondering what your reactions are about this relationship. I know people get weirded out by the age difference and I have no idea how I'll break it to my parents but it feels like the right thing despite all the negativity towards it. Is anyone else in a similar situation as mine? Did it work out for them?there
