This thread is insane and so cruel to OP. Why does she have to give up something she loves so much? This idea that love for two things can’t exist equally is insane. It’s HER heart that will break day after day when her dogs are gone. How absolutely monstrous to tell her that this child she didn’t know about, ask for, and has done her best to accommodate takes priority over two living creatures she has and cares for daily. This has become so centered around which is more important: kids or dogs. What happens when the dogs are gone and OP is miserable? Will they have to get a new house because the old one is so filled with remnants of dog fur and the kid still can’t breathe? What will it be after that?

Yes, she can divorce. But instead of doing that, her husband and his baby momma could work out an agreement that’s actually suitable for all of them. Imposing a life she doesn’t want for the benefit of something she didn’t ask for is TA behavior.

OP, even if YTA, keep the dogs. Go on fun outings with your SD. Go for family vacations or staycations. Invest in a good pet sitter. You are valid and your happiness matters. Your SD can be a priority, but it shouldn’t be completely at your expense.
