Am I overreacting? 20w pregnant, family issues.

ka

My parents don’t support my husband I having a child together. I’m currently 20 weeks pregnant and they don’t approve because we lived together before marriage. My mother wanted to still throw me a shower, but her and my dad aren’t fully sold on it because I had sex before marriage. I never asked for them to throw us a shower. I never even expected it, but to come out and say “Well I was going to throw you a shower but in my day people threw showers for those who waited to have sex until marriage and then had a baby. It’s wrong to celebrate this way. People will talk.” I’m not some kid who just moved out. Ive been with my husband for 4 years (going on our 5th year). Now don’t get me wrong, Like I said I never expected anything. However, they threw not one but TWO huge showers and spoiled my brothers first child. My brother also lived with his wife before marriage and they knew this. How can you judge me and outcast me when he did the same thing I did? Am I overreacting?
