Hello, this is long!
I think I might tell DM about sexual abuse by family friend when I was about 3. She has no idea AFAIK, and I have been remembering things for about 18 months so she has probably been wondering what the hell has been up with me for the last year or so. I have been severely depressed at times and it's been really obvious.
The complication is that she is a bit toxic. She has no concept of boundaries I.e, will turn up at mine unannounced several times a week without giving a thought as to whether I actually want company or not. She is passive aggressive and sulks quite a bit, but will not address anything directly. She also hates if I have a different opinion/approach than her about anything, she takes it as a personal insult/rejection.
Basically she sees me as an extension of herself, has no respect for anyone as she has none for herself, and is very messed up due to her own childhood. I have no doubt, however, that she loves me.
I want to tell her about historical stuff just so I don't feel the weight of the secret anymore. It's exhausting. Also, I want her to stop dropping in all the time as I find it intrusive. My plan is to tell her to phone first so I can say 'yay' or 'nay' to a visit, especially if I'm having a grieving day.
I want dsis there to be mediator. If she reacts badly there will be someone who knows about it to calm things down. I'm prepared for initial shock/denial/minimising etc. If she does this I'm happy to reduce contact to a minimum for the foreseeable future. If she is supportive then that's a happy bonus.
Any advice?
