I'm 23F and my partner 24M are together for over a year. We started living together pretty early on (around 7-8 months into the relationship). I'm coming here because i feel like I'm going crazy. I don't know what to do. And i really need advice. My partner is bipolar and has a drug addiction (predominantly cocaine). He is in therapy for around 2-3 years, he was also medicated but he decided to stop over a month ago (he felt like he lost his spark and was constantly tired and hungry). It was very manageable for both of us for majority of the relationship. But now it seems that he stopped caring about everything.
Before hand, I apologise for the structure, I was crying a lot and my thoughts are all over the place. And also a new account because I don't want to be identified by my friends.
For context, he failed majority of exams, and his parents were not/and still not supportive. They are acting very unreasonable and immature. His mother constantly asks if he mentally slow but in a harsher way. His dad says that he will not support him financially when he fails the next exams. I have tried to motivate him to study and do the practical things for his studies but it seems he just gets more annoyed and frustrated at me. We have been having tough conversations (even before the exams have started, I completely understand that academic stress can make into a complicated and stressed out mess) because he is treating me with disrespect, crossing my boundaries (emotional and physical), when he doesn't get what he wants he pushes me (not hard but you feel it and take notice of it). I try to speak up when he crosses my boundaries and sometimes he listens and is present or he is defensive, stonewalling and dismissing my feelings and calling me dramatic and etc. and now he started asking if we need to go to mental hospital.
Tying this to the title. I have noticed that when he does listen, is present and acknowledges that he hurt me and is not defending himself, next day he gets very cold, entitled (mainly to sex) and says hurtful things (be it in regard of me staying more at home, me crying, word hate being thrown at me, etc.), dismissing my feelings by saying that i just needed to let my frustration because I'm not so active with my friends (it is true that I didn't see my friends for a while because of health issues, writing and finishing my thesis, and me preferring to be alone at times. I love to be by myself and do my hobbies and whatever is needed. However, now I'm more active then in winter). And then the third day he acts like as if nothing has happened. He gets confused about me being still sad or wanting to sort things out. He then sometimes gaslights me that I'm making a big deal out of something small and so on.
I know he can be the perfect person, that cares, loves and does more than the bare minimum. I saw it and felt it. I don't know what has happened, I don't know what to do for my mental health and how to make it easier and better for both of us. I really am crushed and broken. I feel really exhausted. I beg you for any advice. Thank you for reading and I'm looking forward for your replies. I hope you are doing well!
