My cheating ex is getting married and wants my kids along

Because we share time with her 50/50 and we split her day care costs, I have not involved lawyers... yet. But I did meet with one the other day. Confused, not sure where to start, he suggested a mediator.

You sound really bitter. Yet you have 3 children from 2 different men. Not judging you, but you must realize objectively it looks like you don't make the best choices. Whatever else you do, don't make your children pay for your frustration. You chose your life, they didn't get a say.

My advice to you would be to step back and try to let go of your anger. Sure, your exes are probably both jerks. Maybe you were too. But somehow, your exes are able to move on and find happiness (even though they are away from their children too 50% of the time). Take Miso's advice and fake happiness until you truly feel it.

In that case I don't think there's a need to involve courts/lawyers.
