Lonely SAHM no friends

I honestly thought I had friends. But lately they don't bother messaging me or anything. They have babies maybe just a year younger than my youngest and I guess they feel closer? Idk just sucks because my kids don't really have friends to have play dates with and I was really looking forward to having playdates 🥺🥲 anyone else suddenly dropped from friend groups? Idk if I did anything to upset them I don't think I did but if I did wish they'd tell me 😥
