We are still here, yes ?
Even though you shout at us 
You are quite hard to help on here, because you present your story in pieces and soundbites
Could you put together an organised post and put it in relaionships ?
Sort of like a summary (without the shouty bits) of the bad experiences you have had with blokes
Can you recognise a pattern and/or triggers ? Can you articulate it ?
Your own thread, a reflective and calm one, might help
It would certainly be useful for when you see a CBT counsellor to have explored, if only superficially, some of the bargains you have made with yourself for the sake of a relationship with a man who was never good enough for you in the first place ?
You shouldn't blame and castigate yourself, try to get to the bottom of it instead
Does that make sense ?
