Thanks everyone for the advice.
I do agree, and after lots of soul searching I have decided to take a massive step back from it all. I think the time has come where I need to look after my own mental health.
I hope that doesn't come across as self centred. It's not that I don't care. Far from it. It's just that I have enough to deal with myself, and their issues really, are nothing to do with me.
It's hard. In some ways I know I'm probably one of the few 'normal' people she knows. I know I'd be able to find the compassion to help her.
But I think it runs too deep and I risk getting dragged down with them, 'used' as part of their horrendous games, or could even end up being blamed for whetever events are to unfold next! I could really see that happening.
So my focus is, and will have to remain, on me and ds.
In the meantime, if I am as concerned as I was last night, I think all I can do is simply let H know in a brief text or call, and then leave them to it. I've been saying about changing my number for a while. (Never did because I wanted H back so much and I knew I needed to keep the lines of communication open with her so I could find out if he was up to no good again! How messed up is that!) But all that has changed now so time to actually do it I think.
And macd thank you so much for the advice. 'Histrionic' sums her up perfectly. Really has given me food for thought.
