My dad lives together with her mom. Nothing blood-related.

Came into a situation over the summer where I was going to take care of my dads dog over two weeks while they were gone. So I had the apartment for myself during that time. Apparently my stepsister was coming over the summer as well to work, during the same period for two weeks. So two adults, stuck together under the same roof for two weeks.

Anyway. Was great. We were laughing over the situation and it ended up having great time over that period and had a really good chemistry. She's a psychology student in her fourth year and we were laughing at how our parents relationship is a disaster on how they handle things and everything. Also got into some discussions about drugs and how we both wanted to try acid. Perhaps together at a day when we were both free and before our parents got back.

In the end, I didn't really wanna pursue anything (physically, I had plates still that I was seeing during the time we lived together) because of the situation and respect for my father so shit wouldn't get weird. But it got weird. She started talking about how she's never been in a relationship before and opened up quite a bit. I never validated her during these weeks, we were just hanging, I was mostly making fun of her and we just enjoyed each others company, lots of eye-contact, I was always being able to keep it longer until she had to look away with a smile.

Apparently during this time, stepsister had been texting her mom how much she actually likes me, how she's never talked to someone like she talked with me and shit. It felt genuine somehow. And her mom told me this at a later point when I was alone with her. God damn.

So our parents comes back, I got a few more days left there -- and it's midnight -- and we're forced to be in the same room, and it was my birthday as the clock hit midnight. And in one way or another, she said that she's had a crush on me when I was younger, probably 8-9 years ago. Like she was planning to say this on my birthday. She was literally shaking, her heart was pumping and I sort of didn't know how to handle the situation. I should've laughed it off, but we were sitting next to each other in the same bed, talking, and I ended up lying on her shoulder, taking in the situation and I could feel it. I'm like fuck. Lots of tension has been built-up, especially when she drops that bomb as well. I ended up kissing her, making out with her, touching her everywhere, it was insanely passionate, I don't know. Thing is, the walls are super-thin and oh yeah -- her little brother was sleeping in the living room. I forgot that detail. They could probably hear all of our shit we were talking about.

Fuck. I really started liking her. I had a few plates already that I was seeing, but this was different and ridiculous. Exciting.

So anyway, few days left, stepsister at work, I was alone at the house with her mom, she was kind of drunk and she said that I should say stuff that I actually appreciate the time I spend with her and shit. I knew that it'd backfire. And after that night, she flipped a 180 and became distant. And that sort of made me want to say it. I knew it would backfire, and when I always held frame during our two weeks, this time I fucking broke it and said that I enjoyed what happened during that night and wondering what's up -- sort of shakily as well, 'cuz I knew it'd backfire. LOL. So ridiculous when I'm writing this. And we had to share the god damn same room for the next few nights as well. She rejected me when I said it, obviously and said like "yeah it was cool" and tried to get the power for the ego right.

Anyway, I sort of sucked it up and said the next night as we were busy doing our own stuff during the day and said that "oh yea, about last night, that's on me -- or well, actually, whatever I said yesterday, the bill is still there you gotta pay for".

After that, I never really got anything more, just everything dulled down. I said to her one night -- again, wondering what's up. Stupid of me. Needy af. I'm aware of it. The situation with her mom telling me everything my stepsister told her, and the stupid thoughts that had been going on in my head... yeah. Ended up with me saying that if you don't wanna talk, you don't deserve my attention, and that was it. Went silent. Never really talked with her again, it was weird as we were still having to live together and share the same room for a few more days before I was leaving. I just ignored her and went on doing my shit.

So time was for me to leave, to move back to my city on the other end of the country. Family was in hallway, along with my stepsister. I said goodbye to everyone, gave everyone a hug, my stepsister as well, and she looked deeply into my eyes, and I into hers, for the first time probably in a few days, I patted her gently on the shoulder and said bye.

While going out, the dog, her mom and my stepsister were on the balcony looking out while I was jumping into the car. Fuck me.

Now my dads 50th birthday is coming up. She'll be there as well. As well as my sisters best friend that I ended up fucking and ghosting. FML.

What to do? LOL. GG.
