Yep same here. I had a big group of friends which half had kids. And towards the end I realized that they weren't really "nice people" and didnt want my kids growing up with them. But some of the others we loved but were still in the party stage and wasn't interested in kids. So we've grown apart.
It sucks and is really hard. I have my family and partner and no "friends". But wouldn't change it for the world. Its like finding the write man in a way haha. We'll all eventually find a good group of women that feel the exact same. Like we have in this forum but hopefully next step is in the same town lol.
