Friendship?

Ok I need advice... this is more about friendship then relationship problem but I don’t know where to ask or post this problem I have.

I recently made new friends. A group of first new moms I pretty much put them all together because I felt like we all get along and we are young with out first babies. So, we hanged out a few times everyone got along I thought we were all good. But one of the girls from the group that I met first told me that one girl said that I was “weird” she said this too the group with out me being there of course. She told me that she said that I’m awkward and weird because I don’t complain about my relationship with my husband and everyone else does. And that I’m very private that she thinks that I’m weird also that I baby my baby too much he is 5 months. Anyways, I felt kind of sad because this girl talked behind my back. This is my first time having girlfriends. I was homeschooled so I don’t have many friends. I just feel a bit sad about the situation. Am I overthinking it? Is it really weird that I don’t talk about my relationship? I just don’t understand. Then also she talks to me like she likes me and doesn’t have a problem with me like if she doesn’t talk behind my back like being two face. I don’t know what to do.. she I stop hanging out with the group or just say something?
