How to handle the disrespect

[Biscuits]

Ok so here's is the issue , this is our story. He was my best friend in high-school we talk about everything together and soon those crushes turned into love . We dated for 2 and half years but he often verbally attacked me caused me some ptsd he was always telling me everything was my fault that I couldn't talk to other guys or it was disrespectful to so honestly its something I learned that I was kinda of doing I would keep up long term relationships with other guys and other relationships taught me it wasnt really ok so i keep my interactions to a minimum when im with someone just out of respect for the person.
Anyway he left me after 2 years of torture, I was soo numb . I knew he was leaving me for her because I saw their interactions together and he was so excited about her .

He stayed with this women for 17 years and we reconnected ...I realized how much I missed him . Missed the connection and deep friendship we have. My husband and I have an open situation so we were able to talk and im allowed to date. I know tototal 180 right my husband and I are happy its just something we enjoy but we have a rule I can only have one other person so needless to say I chose my ex again. Which I usually never go back to an ex but he seemed changed and different this 17 year relationship had changed him. He was sorry for everything he'd done. He left that women and we decided to add him to our thing going on .he requested to be apart of it and through it we find out he has bpd.

I became a one women research team and started reading every book I got my hands on . I was sad because I feel like if I would have understood him when we were young he wouldnt have left in ther first place. Regardless  I wanted to understand,  now mind you I have major anxiety and panic disorder.  So im sensitive. 

I know he had a favorite person right now and its not me and im trying to deal with that.hes allowed to talk to whomever he pleases but there is one women at work whom he keeps talking about almost to the point of inappropriate amounts and it was making me uncomfortable. I asked him to please stop or just censor what he chooses to share with me about her. I realize this is his job and shes his boss so she will obviously come in conversation but it hurts alot because he seems to happy and giddy about her. I keep asking him to please just tone it down and to just mind what he says because it will trigger my anxiety.  Its the only time ive truly censored him.

He keeps getting aggressive about it . Now to note im speaking to no other men and no other man has left my lips out of respect. He keeps accusing me of severe jealousy threatening to quit his job . How im ruining the friendship we have . I keep telling him this behavior is hurting me . He said he would tone it done and has . It made me feel so much more comfortable and he would just talk about work situations with her and i was fine.

Last night we go out to dinner since we dont gwt to spend much time due to the terrible hours at his job abd he works hard and ive been sympathetic qnd I cater to basically his ever need. He begins to ask me to to be an " easier" girlfriend that he doesnt want to realky have to deal with my emotions when he comes home deal with my moods when hes home.which hurt alot then he states that he wishes he could talk freely about this women. I got angry at the table but calm and tried to explain my case foe the 5th time because I felt he just didnt get it to which he got angry in return to the point where he was crushing the bread and accusing me of ruining that part of our friendship and we will have nothing to talk about because she is at his job.

Note I dont care about work situations I care that hes talking about " sitting knee to knee with her in golf carts and how his eyes light up when he talks about the kind of coffee she likes." Its its just alittle disrespectful and it hurts alittle so i tried to set a boundary and he keeps trying to push it and verbally devalues and attacks me when I do. I just want this boundary to be met and for him to understand that and once I feel secure he really wont hear much else from me about it but he keeps pushing so it keeps making me insecure. Im just trying to understand how to deal with the disrespect and im trying to understand his side but if he said somthing was hurting him id do everything in my power not to do that..

Each time I try and set this boundary its a huge fight and a problem . Im at a loss .
Tbh its really hard for me to deal with the devaluation and constantly having to manage his emotions but he cant do this one thing..I feel disrespected and hurt and tired

Note : he agreed to this open relationship but the same rules apply to both Sides he can randomly do as he pleases but always come home and we remain priority but he is making this women seem like a threat to that priority..behavior changes constant talking about her, dropping everything to help her. I dont belive this is a romantic thing but im just asking to please respect the boundary I set and when he was it made me feel so much more secure and relaxed and i didnt worry and there was no more issue no more fights but he just keeps pushing it.

Idk what to do  I know its a complex situation but I wouldnt react this way if I didnt feel threatened.  Hes talked to other women in the past and it hasn't effected me except for his ex while they were breaking g up he pushing boundaries with it but they were more set for him so he could heal but its a mess.
