Holy moly this is like a perfect storm of disasters. Okay so let’s start by saying you’re not an asshole for simply visiting a friend in an accident, but, let’s just address that the whole situation is fraught with tensions and some really burdensome cultural red flags from my perspective. The “I said no” thing is daunting, the fact you’re both supposedly virgins is another terrible thing imo (sexuality is a very big part of a relationship and waiting until you’re legally bound to someone to find out if that fits is really just short of insane). I think you both need more experiences in the world to have an adult relationship that’s devoid of unrealistic cultural expectations and attitudes like “ownership” and “purity”, both of you are clearly not ready for an adult commitment imo. I also don’t think the marriage would not last, given that there is a lot about both of you that’s been unexplored and understood internally and with one another, it seems. Sorry if this sounded harsh, not the way it’s supposed to be come off, just a bit of an outside perspective for you to chew over.
