Is my boyfriend cheating?
Lately my relationship with my boyfriend hasn't been a healthy one. Less than a week ago we were fighting on the phone until 8 in the morning b/c he kept asking me how many guys I've hooked up with before him. When I told him, I told him I wanted to know his number as well. I was shocked b/c he said 12 girls. So now I have the image that my bf is pretty much a player. (btw, his 26). Tonight, I went over to his place and found a girl's hair clip in on his bedroom floor. I asked him whose it was and he said he thought it was mine. Then I got really pissed and started asking him questions and he swears he doesn't know whose it is or how it got there. He says maybe his cat got into the closet where he used to keep his ex's stuff.
Is he cheating? How can I tell if his telling the truth?
