Mums seem to hate me because I'm not like them, do I give up on finding friends?

Long story short, I am no longer in any mums groups because they have been extremely toxic. I'm usually more of an observer, I try join in occasionally to offer some help or advice but everything I ever shared about myself was always met with hostility, jealousy or attacks, even to the point where I've been removed from groups simply because one mother didn't like my opinion about something. It feels like I am expected to be poor, have an abusive husband, hate my pregnancy and be suffering in order for anyone to actually like me. I have made effort to meet with other mums and do whatever I can to uplift, listen etc but I suppose they are just not my people.

I am not like most mums, I have several of my own businesses that I built from nothing, my husband is a SAHD, he quit to free up my time so I can continue to grow our businesses from home. My husband adores me, he treats me like a queen and I loved pregnancy despite it being high-risk and having lots of challenges throughout it. Apart from the sleep deprivation I had before my husband quit his job (when bub was a newborn and after paternity leave ended), everything has been relatively easy other than feeling tired. I haven't dealt with hair-loss, PP depression, mood swings or anything like that, in fact, I feel great considering I am over 40.

I would absolutely love to find other mums that are either creative, have their own business or have a happy healthy marriage, as I feel those are things I never have in common with other mums. Does anyone have any ideas where I could meet mums that enjoy life and are happy with themselves and don't want to bring others down for not being depressed?
