My girlfriend and I have been going out for 7 months at this point. Now, in that time, I have never heard her dad say anything nice to/about me. he's hated me from the start. This dislike for me has recently been kindled into an inferno when he found out we are having sex. Now, I'm 17, she's 16. in my state, 16 is the age of consent. It's gotten to the point that when I dropped off a birthday gift for my gf, he threw the door open damn near breaking the thing in the process, and screamed at me to "get the **** off his property." (he's renting the house, so it isn't even technically his.) Later in the confrontation, despite the fact that I haven't said a word during, he threatened to "get some friends and come to my house to kill somebody." I have no idea what to do about this. Any suggestions?
