To those of you who are saying "Get a grip, suck it up, stop crying boohoo...". Fuck you. Seriously. Just fuck you. Because if you read the whole thread, you will know that I have been more than dignified throughout. I do not say anything nasty to DCs about XH or OW - I save that for my friends. I willingly agreed to DCs spending the whole of xmas and new year with them and never uttered a peep. Not to the DCs and not to XH. So i'm not constantly throwing tantrums, thanks.
My DCs know who she is and what happened and they know I don't particularly like her. But I have also made it very clear that they are entitled to their own feelings. That it is really OK if they like her. I think they are mature enough to get this.
I do not claim to own another person's life or behaviour and what I did in the end (after venting on here for a bit) was make a request of XH, which he granted. I do know this is the shape of things to come and I AM dealing with it. But in my own time. I love my DCs, i know how much they love their dad and their happiness is my priorty. But I think I also have the right to look after myself and put some boundaries in place if I need them.
As for OW not being bad people. I disagree. Unless the OW truly doesn't know what she is getting into, it shows a basic lack of morals and respect for other human beings. In my case, OW may be perfectly nice, but she also knew exactly what she was doing. She knew he was married with children. She had been in my position when her own XH cheated on her. And when I met her once, during their affair but before i knew about it, she had the nerve to look me in the face adn thank me for being so supportive of their "friendship". And then she hugged me. So I feel justified in thinking she is basically not a very good person at heart.
As for "being dumped" - I think that being betrayed by your partner of 18 years and who you genuinely thought you would spend your entire life with is more than just shitty. It is truly traumatic and life changing - as some have said, similar to a bereavement. And yes, you..I, still have to get over it and move forward. I am. But not all at once and not on someone else's terms. I am actually a trained counsellor (tho not working as one now) and the one thing I came across over and over were people coming to me after a major life tragedy and saying things like, "but it's been a year, it's been two years or 3 - I thought it would be better by now." I learned that these things often take a lot longer than you think. It doesn't take as long as someone else thinks it should. It takes whatever time YOU need to process it. I'm working on it. I've worked on a lot of it over the last two years. I accept their relationship. I'm starting to accept that she is involved in my children's lives, although that bit is still really hard. And now I will have to work on her having some kind of presence in my own life. But I don't have to do it just because she feels like watching my DS play football (it's not as if I banned her from his wedding!). I will do it when I'm ready.
I also agree with the poster who said that there is no reason the new partners can't show some respect for the other adults involved. If, as folks on here keep pointing out, she is going to be aroudn for a long time to come, then there's no rush.
And I will definitely remember face like a grieving cod when I eventually do come face to face with her again. Am sure it will make me chuckle and she can wonder why.
