Recently he sent me a friend request on facebook....

After a second or third date, this man starting yelling at me and pacing the floor saying that I was not normal because I had not yet gone to bed with him since all his other dates had jumped into bed with him. This person hads lots of friends where I worked at the time and seemed to see me as in the wrong... I have felt so confused about this for a long time why people would see him as an ok guy when he does things like this to people...
Should I become part of his friends group on facebook or run for my life?
