Should I marry my girlfriend or just keep dating for fun?

Anonymous
So me and my girlfriend have been dating for a total of 7 years on and off. We have a few problems we can’t really fix I want 2-4 kids but she only wants one child may be willing to give me two kids. She has ptsd that related to kids but refuses to get treatment for it so I don’t truest her enough to have a child with her till she gets treatment for her condition. She refuses to get treatment since she thinks they will put her in a crazy home long long story.

I have notice her ptsd is only trigged when she sleeps at her parents house or when people
Bring up our unborn twins that died. I have voice my concern with my kid about how important it is she sees a therapist but she won’t agree to see one. She has done something pretty much up because up her ptsd THat I can’t forgive then on top of that she kind of like to cheat in small ways but can’t even remember doing it or don’t see it as cheating. It has never been anything physically just sending Bikini photos to a friend I dislike which she don’t even remember doing. I would say the only issues she has to worry about with me is I have a really high sex drive which I’m in better control of since I’m seeing a sex therapist. I I’m not a sex addicted but I could easily have sex 2-3 times every single day

With no fights and the issues with kids all started after her parents beat her up killing our unborn twins.. been 4 years since this and she won’t get any help for it. The guy she sent half naked photos to lives 16 hours away by car from us and I known him decently will. He’s a fat loser that ex friend of her that I made her block but on n off she unblock him for the past 2 years since the whloe ptsd stuff
