something had come up from his abusive past which had totally thrown him and he took it out on me, he just briefly said sorry for what he had done to me.
How did he take it out on you?
There are symptoms of some other disorder but as to if I should give it a name or just see him as a person with a lot of troubles which very few are aware of.
Are you a clinician? If not, I would be very careful about taking things to the degree where you are attempting to diagnose him yourself. If you are a clinician, I would be even more careful as loved ones can often misdiagnose fellow loved ones.
He also played with my mind during that time by turning social media messages from read to unread and while ignoring me, he was out at parties enjoying himself no matter what he was feeling inside - I was the one he took that out on.
By shut out, do you mean you broke up? And he continued to have a social life after you broke up? If that is what happened, I'm not sure that is a sign of pathology but a possibly healthy way to cope with pain. if it is PTSD related, shut outs commonly happen with the closest people, because those are the most vulnerable and intimate relationships. It's easier to engage more distant relationships. It's generally not a manipulation even though most supporters seem to generally feel that it is. He may be the exception to that.
He does have what I would call bad social skills but again, very good at covering them up. I'll ask him to text and he will ignore or send a message when he knows I'm not on the computer, if annoyed things like this are worse. T
How do you know he is intentionally sending him a message when he knows you are not online?
He didn't understand why so I emailed him being very specific but kind in what I said to try and explain things and how others see a different person to the one I do - they have no idea at all.
You are adamant he has poor social skills. That may be true. Some would consider it poor interpersonal skills to email a partner, a loved one, about an emotional disagreement. SO MUCH can be taken the wrong way on text and email. It's been said that 80% of communication is non-verbal, and not only is it non verbal, but when it is on email, the other party can read so much into it. I know a lot of non-PTSD people who do not have poor social skills who never work out disagreements or emotional matters on text or email, or who generally suck at responding to text or email. This is especially true for email.
I am beginning to feel like you possibly over-pathologize him a bit while overlooking your own role in the problems in the relationship. You have chosen to date and break up with and date and break up with the same guy, instead of finding someone with greater emotional capacity to be there, consistently and steadily. I think it is great that you are working to accept him as he is, and not change him, but I am a little concerned thath your way of trying to cope with his behaviors, which are exhausting no matter the cause, is too much focused on finding this or that mental disease process to explain them. Maybe you are over pathologizing because if is a mental disease that makes him t his way, it will hurt less when he does it?
It's hard to say either way based on what you have communicated here. It does seem clear that neither of you are interested in getting therapeutic support. I would like to suggest that you re-consider getting support for yourself to look into why you are drawn to a relationship with someone you feel has more illnesses going on than he is willing to work on or deal with and someone that you feel is intentionally manipulating you so much and so often. If he is really trying to manipulate you this much for so long, why do you stay?
All of this being said, if he is taking out any of his symptoms or anger or anything else on you in any way that puts your safety in danger, drop everything and run from the relationship. Whatever is going on for him, it's not an excuse to abuse you. Period. Be safe.
