My cheating ex H hasn’t yet announced having a baby with OW, but I know it’s probably just a matter of time and I’m trying to prepare myself for it.
I am surprised at how negative some of the poster are, after you are only human and you were with your ex for a long time. He is the one that behaved badly. I feel like these cheaters just feel like they can do what they want and there are no ramifications. It feels like their behaviour is condoned by society largely.
I have no idea how I managed to rise above my ex behaviour but I have done and have even managed to take the kids to some things with him. I never thought that be possible but I see how happy it makes my kids (they are littler 2 & 4) and I feel so proud of myself and it honestly helped me heal to know that I’m doing the best thing I possibly can for them. It’s also helped me move out of the hate bubble relatively quickly. However, I am not as far on as you and I 100% would be saddened if my ex had a baby with the OW. As she would then be tied to my babies forever....
I agree with those who have suggested, have as little contact as possible and only re the kids. Be as civil as possible in front of your children and try and speak positively about the baby as this will be your children’s half sibling. Make it as easy as possible for your children. What I’ve found is you can totally “fake it until you make it” just pretend to be civil and pleasant and the weirdest thing happens it gets easier.
I hate what my husband did, he too tried to rewrite history well recent history anyway but he gave me my two beautiful children and many happy years feeling loved, so for that I will always care about him. I craved to feel indifferent but I don’t think that will ever come for me...
Good luck and I hope you can find the strength to help your children through the crazy emotions that will come with a half sibling arriving
