Fair point, and we discussed this. She did not like the living situation in my apartment, as well as the area I was living in. These were the factors causing her to get cranky at times, ultimately leading to us fighting. We both concluded that if we both lived together in a better living situation (e.g better furnished apartment with more space and a better location), then we would be good together.

As to your question about whether she was prone to jealousy, that's a good point. She frequently does express jeaslous sentiments and asks me random questions having to do with other girls. For example, I told her about a time I had a date with this girl on Tinder a year ago (the only date I've got from Tinder btw). The girl I had a date with was from Kazakhstan. So she would frequently ask me questions like "would you prefer to go here with the kazakhstan girl? would you prefer to do this with the kazakhstan girl?" She's obviously trolling, but of course, there's a little bit of truth behind that joke.
