Search Results: do most people cheat

I've been dating my girlfriend for almost five years now. She is my friend's youngest sister. I'm 28 and she turns 20 this August. She hasn't gone to college yet because she wanted to take a few off to figure out what she really wanted to do in life before rushing into a college program. I'm afraid that she'll grow apart and distant because she will probably live on campus and go to parties without me, and probably meet another guy. I know the relationship I have with her is longer than most people stay together now. Even married couples probably don't make it past a few years now. But if she has a baby then she'll focus more on the kid than other guys. I'm fine with supporting her and she already told me she doesn't really believe in abortion. She only thinks abortion is acceptable if a girl is raped, if incest was involved, if carrying the child would end the mother's life, or if the baby had something like down syndrome or some other problem. So if I get girlfriend pregnant she is definitely going to keep it but I know she doesn't feel ready to have a child. What should I do? I'm really afraid if I don't get her pregnant that she'll find some other guy when she starts college in September. I haven't talked to her about my concern she will meet some other guy but I know most girls would probably leave to experience other guys. Should I ask her to marry me instead of getting her pregnant? If she says she isn't ready to marry then do I get her pregnant? Like, if I get her pregnant she will keep the child and most guys in college won't date single moms so I know I'd be safe. She wouldn't go to parties too often either. I don't think my girlfriend is a party girl but when girls go to college and live on campus, it changes most girls. I really love this girl so I don't want to lose her to some other guy. All the other girls I dated cheated or they broke-up with me to experience other guys because YOLO. One of the girls that broke up with me really told me that was why.
