Damn Lockins During Pandemic

I was locked in during pandemic in a country that took the lock down very seriously. I shared an apartment with a very rich classmate of mine. I could never afford anything like the apartment she had, and I only paid 100 euro a month to her. No job, no income and she said I didn't have to pay rent. It wasn't a ploy, but we were both pretty horned up and one night over wine, some porn on the TV (it's shown on broadcast in that country after 10pm) and I was having lesbian sex. We stayed like that for almost 2 years. I caught the first flight home which took another several months, and finished classes, and met a nice man and we dated. He was the first man, and only the second person with whom I had sex. My lesbian seducer was my first, which included her "Popping my cherry" as she called it.

I never admitted it to my boyfriend, I pretended that it hurt going in the first time we did it and he thinks it was him as my first. My ex girlfriend comes over to the states and staying with me started sleeping with me again. At first it was just sleeping, then it was sex. Then she told my boyfriend that she was my first and had "popped" me. He looked at me stunned, she continued prattling on about how it was so nice to catch up in bed with me.

He wants to leave me, she wants to marry me. ???????????????
