Should probably have name changed but what the hell. I think I need help, I'm hoping I can get some perspective on my behaviour. After a long single spell, I've been back in the dating pool. I've just parted with man I'd been seeing for a few weeks. I reacted badly as felt he was criticising me (again) when he was teasing and I have 'no sense of humour'. Regardless, there were a few red flags and I knew it was not working at an early stage.
The issue is that both he and previous bf (a lovely man but with serious issues) said the same thing, I always come out fighting, will always argue black to their white. So there have been two very different characters telling me the same thing. I'm also worried about the similar way both relationships ended with me being shouty on the phone with "back the fuck off" to Red Flag Man and "please, please stop arguing" to LM 
My background is single parent of DS18, father never was around. 2yrs ago I left a high pressure professional job after crumpling with bullying boss. It turned out I was not the only one but was her favourite. Bullying started after I was off sick with breast cancer, if anything the bullying did more damage. I've realised I've had abusive relationships in the past, early marriage years ago with severe EA and DV. Had DS mid 30s, since then one LD relationship with a narc, a couple of other short term LD relationships. Put relationships on hold to concentrate on DS, health and look after myself. Most of the time I've been single, I like my own company and my friends.
As background, narc tendancy mother, think I picked up a few traits along the way which I have worked on unlearning. DM is emotionally cold as ice, she is elderly now and getting dementia so no chance of any resolution. Although I think she is proud of me, I feel I am not the 'naice' daughter she wanted. I'm mixed race but racism was always denied at home. Calling anyone it meant I had a chip on my shoulder. Only child and always felt different and isolated, was generally unpopular and I didn't know how to behave socially. Labelled 'difficult' by authority until I went to University and was suddenly very bright instead
.
I have good relationships with my friends, although I have let too many friendships slide over the years and I'm not great and staying in touch. I'm seen as the strong, sorted one. I've worked on myself and apparently I'm fine now socially.
So there is a pattern of me attracting abusive partners in the past, and then the work place bullying. I have also had very low self esteem for most of my life. I am learning to value myself now and I am making better choices in life generally. With relationships I'm at least spotting the red flags and instead of sticking with it, thinking I can fix them or putting up with stuff because early I'm 'difficult'. I'm recognising when it is not right and know when I deserve better.
I think I value myself now but it seems I may be fighty and agressive. I know I'm shouty, but I'm not nasty with it. I do know I'm defensive. I seem to have gone from taking everything to heart to erecting boundaries with spikes on. Yes I need some sort of counselling to think things through but I have a gut feel that I'm missing something obvious here. Please forgive typos in advance, dyslexic and I can't always see them reading back.
