I'm a SAHM who realizes her friends aren't real friends

They don't ask me about my new baby. They don't ask me to take photos of them and instead hire other people. They don't respond to my posts online yet respond to each other's often. They like to say "no mom judgment here!" jokingly. But I feel they're judging me for I DON'T EVEN KNOW WHAT. I had texted them saying I was having a tough day. I never got a reply from any of them. They're all ignoring me. Why? Someone had left the group amicably before. Now I know why.

They say it can be hard to find a good man to marry. Well, I find it hard to find good friends. Who else can relate?
