Am I overreacting?

I need impartial 3rd parties.

If you're a man in your 30s, living in a bedroom of your younger brothers house, who has a wife and toddler, is it acceptable to bring random women home from the bar without talking to your brother or his wife first?

I'm the wife, and I feel majorly disrespected.

The first time this happened I asked my husband to talk to his brother about not allowing strangers in my house. My husband asked his brother to text me first. It happened a second time, without a text or anything before or after, and my husband is telling me I am wrong for feeling very disrespected.
