He never met any of my family/friends at home, just my mom and one friend we had mutually. She though he was a great person, and said he would be a good boyfriend for me. I know she really liked him as a person, and I took that as a sign when I started dated him that he was a good person.
I am not really friends with any of his other friends, but yes he has friends. They tend to be...drinkers and well I don't drink so we never got together and I never met them.
I met one of his friends one time, they hadn't seen each other since high school.
I don't have any real reason to believe he might be violent/aggressive other than those on here who say he does have red flags for an abusive person. The night I left/broke up with him he was very angry though and said something about wanting to hit a wall, but I got out of there and didn't hang around to see if he did of course...
