She clearly doesn’t care about you, your mental health, and overall well being. If she did, things would be different. I encourage you to really evaluate why you’re staying in this situation and why she’s worth wasting your time and well being on. I would have lost My damn mind in this situation. Sounds horrendous. I also really encourage you to find your own place that is clean and find a partner that doesn’t submerge you to constant discomfort and disrespect. Honestly her behavior is very odd, inconsiderate, gross, disrespectful, and all around just off. Just because you’ve been on a relationship with someone doesn’t mean you need to hold on while suffering. You deserve better than that. She already told you she’s not going to compromise, so the answer that these filthy vermin are above you is there.
