Brotber In Laws Girlfriend😤😤😤🤬

So yall. . . . My husbands brother,(me and hubby married end of 2020) his brother dated a girl whom we met through for probably almost 3 years(1 before we met). The first time she introduced us was fine but the second she was a thot and we had issues since. Like physically fighting, court cases, harassment, etc. .. . . Well. . . . He finally got rid of that toxic ass relationship after catching her cheating multiple times. Now, hes been seeing this girl 2 years younger than him for maybe 3 or 4 months and my husband and his brother video chat almost daily if not weekly. Never ever has she ever been on video chat with him or been introduced to neither him nor I. Mind you they live 1800 miles away. Well flash forward to last week I heard my brother in law was coming down and then hes here for not even a full day and his girlfriend video calls him. Within less than 2 minutes she wants to talk to my husband about something. She has not veen introduced to either of us yet she wants to talk with my husband? I find it odd. I tried to be polite with his brother when we met and said Hi but I definitely wasnt initiating a conversation between us out of nowhere before we met face to face.

Am I overreacting?
