relationship advice

Kaity
Alright so my fiancé is visiting with his family about 4 hours away from where I am. He had to go Bc of family issues and has been up there for about 2 months. He just texted me saying he wanted to hang out with his brother who is a big drug head (my fiancé doesn't do drugs) and last time he hung out with him his brother tried to set him up with another girl. He said he met her while he was at his brothers house and that's it they didn't talk or anything. Am I over reacting for being upset? I trust him but I don't trust his brother. Should I let it go or what?
