I like this guy and..???

He is really nice compared to the last ones I have been with and I have known him for about 2 years now and he has always liked but he is my dads friend and is 22 years old..Which I have dated 22 year olds before and got pregnant with one but we lost our baby and than got mad at each other than broke and never talk anymore but Trent was always there for me when I was going through all of that (He is the guy I liek by the way). And he finally told me that he liked me alot and wanted to hang out more and maybe date...I like him too but I dont know with him being my dads friend and all what should I do?
