I (22M) have been dating my girlfriend (19f) for roughly a year and some change now. We met at a faculty game night at our university. She was 17 at the time and fresh off the boat and the minute I saw her I knew I wanted her in my life. Things stayed casual for a few months until she turned 18 and I asked her out on a few dates, she said yes. And things became official two months after our first date. She was very forthcoming about her heart condition (type 2 long QT syndrome) and at the time I thought I could handle it. I’d done some basic research and it seemed manageable. But like I said basic research and I had assumed she had type 1 not type 2. But anyway, I convinced her to move in with me four months into the relationship; I received the apartment we live in currently as inheritance from an elderly relative who passed right before I graduated high school, so no rent. I wanted her close to me and I knew she would have a hard time finding private accommodation as an international student. Plus I knew she’d need a roommate anyway because of her health and the thought of her living with a random person made me uncomfortable. Moving on, we started getting intimate about two months after we moved in together. The first time was rocky to say the least but I had assumed it was because it was her first time, her ICD went off twice and I had to give up mid shift. But after the first few times it became clear that she can’t handle more than basic positions and occasionally light choking, and I need much, much more than that. I thought I could compromise because there’s nothing else wrong with the relationship. She’s pretty, neat, smart, meticulous with tasks, incredibly likeable and genuinely pleasant to be around. But our sex life is genuinely bothering me. And I don’t want to just go out and cheat on her.
