I don’t want to have kids , how to find a better woman for my husband?

I don’t want to have kids with him because I’m not in love with him anymore. He’s falling more in love with me every time and I can’t tell he won’t let me go that easy. He makes everything to make me feel comfortable even accepting not having kids when I can tell he wants them. We’ve been married for 9 years. I’m so done. And if I have a kid just to make him happy I will give him custody because I can’t waste my kid preparing another ungrateful human. I love to help animals, kids and I travel a lot so if I get pregnant I won’t be able to keep living this life.

It’s not that easy I need to prepare this guy because I can tell he’ll suffer without me because he’s a faithful old fashioned guy unlike me
