@MoreLegsThanMe I've read both your threads over the past few weeks and have been trying to find a way to say this without putting my foot firmly in my mouth. I think you're doing wonderfully, and it's so good to see you feeling stronger and stronger over time. Your children sound like a great bunch of brilliant people, which is a credit to you.
What I want to say relates to your images of his new life, and I have to say this but worry about tactlessness, as I know, whatever you're going through now, that you have loved him for a very long time, and he is part of your children, and part of your family history.
I can't imagine anything worse that being the OW. She is stuck with a man a lot older than her, with sexual dysfunction (I could do vacuum sex with a long term partner I had enormous emotional investment in, but with a new partner?), now with heart problems. That sounds awful. Then she's dealing with a man who will be, however it is manifesting itself out of your sight, dealing with the loss of the relationship with his own children and grandchildren, and family members - guilt, resentment, hurt. Finally her own relationship with her children is now a disaster zone, and she's spending time with them in a two bedroom flat with her new partner around. Seriously, there are not enough classy throw cushions in the world to make that life OK. And for him, he's coping with all that PLUS step parenting younger children at a time in his life I suspect he doesn't want to be doing that sort of thing.
So when you post about picturing their happiness, I just shiver at the whole set up and how both of them could well be wondering how on earth they disengage from this. If not yet, then soon.
Whereas you have your loving family, your own home, your self-respect and a future that you can build to be what you want it to be, taking your own time to think about your needs. Yes, you are alone right now, but you are totally in control of your life from this point onwards. Everyone who has been in a relationship that ended with infidelity can relate to your worries about trusting again, but so many of us meet someone who makes us realise that there are still a lot of good, genuine, honest people out there. You deserve one of them, and every future happiness.
