I stood my ground and told her I don't wish to know about her relationship with her and to only communicate with me regards to our son
That is very good boundary setting and enforcing SB4G.
I'm now wondering why my ex is behaving in this way?
Relationships with borderlines go through stages, idealization to devaluation, sometimes quickly, sometimes slowly, but always the progression. Their relationship may have gone through the stages quickly, plus the other gal brings her own stuff to the relationship, like we all do, and their relationship will have its own dynamic.
She's also asking if we can be freinds and to stop all this arguing!
The attachment with the new gal is faltering, so she's seeing if an attachment is still in place with you. Borderlines need attachments.
All I do know is she has hurt me way to much more so this time with turning gay accussed me of making her that way and saying it's all my fault
Because the alternative is to take responsibility for her actions, which would likely trigger shame, so it has to be all your fault, when really it's rarely all one person's fault, it's the dynamic of the relationship.
I've told her not to try coming back this time I just hope she's not trying to sabotage the new relationship with my replacement in order to try and suck me back in. I've remained strong so far and continue to do so .
Good for you SB4G! You say she's hurt you way too much, and you're dealing with it by being strong and setting boundaries, a good way to deal with it. And she can only suck you back in if you let her, as you take your power back yes?
