We all live together so i spend alot of time with both of i can . Sometimes he loves me and I can see the hate other times .
but when I get hurt its a physical reaction and im not good emotionally either. Im struggling with my own depression and my anxiety
hes soo centrally focused on himself and his job
Just some ideas on this dynamic. While it seems your boyfriend is not respecting your wish to not discuss his interest in his person at work, consider why this feels hurtful to you. It feels hurtful because you have strong feelings for him. This is normal, it's human nature- and when we have strong feelings for someone and they don't reciprocate them- it feels hurtful.
He has feelings too- for someone else. We can't control anyone else's feelings. His feelings matter to him, just like yours matter to you. What you feel as disrespect, he feels as you wanting more from him than he is able to give you at this time. While what he said about needing you to be an "easier" girlfriend felt disrespectful, but it's also what he feels he needs.
When we are discounting our own needs, in order to meet someone else's, we can feel hurt, anxious, resentful. These are normal, human, feelings.
On monogamy- and I am not being judgmental or moralistic here- there are many reasons for this, and one of them is that when we have strong feelings for someone, it's an emotionally vulnerable situation. Monogamy helps us to be able to be vulnerable in a safer situation- when two people chose this- we worry less about them having feelings for someone else. It's not foolproof- nothing is, but it's safer emotionally.
Monogamy may seem repressive, restrictive- why not be free to love whoever you want, as long as everyone agrees on this? We can choose this but the consequence is a higher risk of feeling hurt, jealous, neglected, when the person we have feelings for also has feelings for someone else.
Think of it like driving. In which situation is someone the least likely to get hurt? When there are red, yellow, and green traffic lights and everyone is driving by the same rules or when there's only yellow and green lights? When you opened your relationships, you replaced the red light of "no other person" - with yellow ones. Yellow lights still have rules and agreements, like you have with your husband, but they aren't as absolute.
You and your husband seem to have a calmer relationship as you both agree on the same rules for being together. Your BF on the other hand, doesn't seem to be "driving" by the same rules completely. He wants an easier, less committed situation- and it feels hurtful. That's understandable but you want yellow lights and he wants green ones.
Whether or not your BF has BPD or NPD- this kind of situation feels hurtful to
you and raises your anxiety. This is normal- and this is one reason why people choose to be in an intimate relationship with people who agree on the same "rules"- however, you designed them. Some disagreements are negotiable- like what to eat for dinner, what movie to see, because the consequences of compromising don't leave us feeling hurt and anxious. This one does- so the choice is- stay with this person, and feel like you do- or decide this isn't something that works for you.
You can choose who to be vulnerable with. This one is hard, because the two of you have a connection from a very special time in your lives- school, best friends, but each of you is older and in another place in your lives now. You may always have sentimental feelings and genuinely care for this person, but being romantic with him caused you to feel emotional distress- then and now. You can always re-evaluate this situation.
