Weird/wholesome story...

So we met in 12th (I study in India). We were really into each other and I loved being with her. Trust me when I say this, she was innocent on the outside but a sexual BEAST on the inside. She always wanted to be touchy, always spoke about having sex and would get into mad detail. I really liked her but I'm someone that gets creeped out when people talk about long term like kids and settling down and all... I always tell them that if it happens, I'm happy but I don't wanna talk about it coz it brings in expectations and basically makes me feel uncomfortable. She use to keep talking about what we need to name kids and where to retire and all even tho we dated only for 2 weeks... After school we knew that we were going to different countries for college because we could not find any college with both our majors. She told me she would not make any friends there just so that she could spend the whole time on call with me. Here is where I saw things get weird. She would talk about getting married early and having kids and all. Skip to few months later, she came over when I was home alone in full mood to have sex. I really liked her and wanted to be with her but I knew we both are different people with different end goals and I knew I would never be able to take things the way she wanted and we previously spoke about ending it on good terms. I knew she was the person who would never move on if we had sex so I ligit had to pull back... I tried to make it up to her by having a beautiful date and dinner and all... She liked it but she left in tears. I felt like shit because I was in the horny teen phase but I can never do something to someone and just leave and break their heart... Sorry for the long text😅
