Should I feel bad??🙄

Should I feel bad for not wanting to invite my husbands side of the family to my baby shower? He's close to his mom + 3 sisters (the rest of his family lives in another state), however, none of them seem to like me very much. His mom talks to me when she comes over to see my 2 & 1 yr old but his sisters call me names such as 'whore' 'lazy' when neither are true. They just have alot of hate. They talk down upon me on social media. They tell everyone that my baby is not my husbands. Theyve all came to my other 2 babyshowers but havnt said a word about the new baby. I mentioned to my husband that I dont see a point in inviting them but he thinks i should..
