I (25M) am a White Brit studying in South Korea currently. I get along real well with my neighbor (34F), who is affiliated with my host institute. She happens to be ethnically half-White/British, half-South-Korean, and she grew up in the UK so she speaks perfect English and relates to me totally. We frequently drink together and she happens to be my type (tomboy, looks like a cute anime girl). She also plays basketball with the kids in our area and she and I run together whenever we can. I thought the chemistry was there. If it matters, she's taller than me and she's also physically stronger than me.

This past weekend, I was spending one evening at her place, and I got drunk but she didn't feel like drinking. She got comfortable, and she took her shirt off and stripped down to only her bralette and jeans (and even though I kinda enforced it, she didn't put any other clothes on for the rest of the night). I ended up getting especially drunk, and I thought that since she was wearing flirty clothes, she was making moves on me. I started subtly doing things like putting my hand on the skin of her back. I mean I thought I was doing it all subtly, but after she took her shirt off, she was sweating heavily for the entire night, and eventually she started crying and asking "what the fuck is this?" She got really scared and I got pissed off at myself, and when she reached for her shirt to put back on, I grabbed it before her and threw it away from her. I didn't throw it far at all, but when I did this, she bent down and hugged herself and started half-screaming and sobbing. She never regained her composure, and she couldn't stop crying for the rest of the night.
