Okay so this will long guys, but I'll to make it as short as possible. I will post a TLDR at the end.

To preface this, I'm aware of the r/deadbedrooms and r/relationships and while I've been reading both of them, I felt like this is the best one to post in. 

So my (f22) partner (m25) and I have been together for 3 and a half years and we live together. During the beginning of our relationship he disclosed to me that he was diagnosed with BPD and was severely depressed with previous suicidal thoughts (i was 19 at that time). This go towards a downward spiral and our relationship was never the same. He got into this tendency of "spoiling" me and giving up things to make me happy and while I asked him not to do that, he insisted. 

Fast forward to 6 months later, he begins to become resentful and bitter, but fails to communicate any issues. A few months later he begins cutting, and tells me about suicidal thoughts. Now guys, i will also add that at that time i was going to college and working 30 hrs/w because he was unemployed. Things became financially and emotionally stressful. Everyday i would come home and worry that he'd be gone, i really didnt know what to do. Now im not gonna lie and say i was easy to deal with, because i wasnt. We were both emotionally unstable.

When it got really bad, i made the executive decision to call his mom and take him to the hospital. He agreed and was admitted for 1 month. During that month, i found out i was pregnant (this all happened during final exam month). 

After he left the hospital we dealt with the pregnancy and decided to abort (mutual decision). I did the pill abortion and it was so excrutiating. I passed out from the pain and spent a long time screaming. While this was happening he was on discord with his friends, and i got upset. I didnt have an issue with the actual abortion, but with his priorities.

In end of 2017, i got diagnosed with BPDII. Which really drove the nail in the coffin.

Fast forward to early 2018 when we are both in school. Out sex decreased and he didnt even want to spend time with me. He explained it as he just got out of the hospital and wanted to find himself after being lost for so long. I understood and was trying to be as patient as possible. 

Ever since that our sex deceased from 1 a week at the beginning of 2018 to once every 2-3 weeks at the end of 2018. 

Now this is where it grts tricky, once his sex drive started going down, he suggested an open relationship for me, i didn't know what to think because i only wanted him. I didnt want to have sex with anyone else. A few months after, i do find someone and have sex with them. It was disappointing and we decide to end the open relationship. 

Late 2018, i connect with a guy that i started talking to when we had an open relationship but we never met or did anything. We mostly talked about vid games and joked around. Later on, when tthings between my partner and i get tough, i start talking to this guy more often and yes this is 100% my fault and i begin sending him suggestive msg/pics. It didnt go any further than that and it was only 2 or 3 times. I would never sleep with him or even do anything. 

My partner found out by going thru my phone. This create big problems, for obvious reasons. While we were arguing he found out that i did t sleep with him or send him any pictures showing anything, so he didnt want to end things, which surprised me. 

I accepted all responsibility and i told him everything that happened. While he told me that he's only staying with me bc its financially beneficial i make around (100k) and hes still in school, we have debts and a car together. 

Recently everytime he brings a problem up or says he cant live like this, i ask him if he wants to leave he says no, and i always assure him that if he did, i wouldn't leave him with all the bills (theyre mostly in his name), he says he only said that bc he was angry and didn't mean it. Im worried that hes only staying with me because of convinience not because he truly wants to. Its not that i care that im paying for the bills, i just dont want him to stay with me because of financial responsibilities. I want him to be happy and not to have to settle. 

I love my partner very much and i honestly hate myself for even doing something like this because he had been cheated on before by his previous ex. 


TLDR; my (f22) partner (m25) and i had a rough patch and i sent suggestive pics to another guy, he found out and stayed. He said hes only staying bc its financially beneficial to stay but later said he didnt mean it. 

I know im the asshole for cheating, but the question is AITA for questioning why he stays? 

Sorry for the mistakes, English isnt my first language.
