I hate my dad he is such a meanie his moods change from one second to second like a flickering flame why is he so mean why is so rude why can’t my dad be kind????? why is my life very difficult to live up to???

So I am in a high school play, I have been doing them since I was 5 years old. I love acting and I have made so many great friends because of it, but there is one who we have both liked each other on and off for a very long time although I have never did anything with him and probably never will. My bf of over a year now gets so jealous of ANY GUY even ones that i have been friends with longer than I have even known him. I am completely faithful and would never do anything to hurt him, but I really dont know what to do. Me and my bf fight all the time and the other guy is going into the army in a matter of weeks. In this play i have to pretend to be in love and do a very fast paced dance with him in it. Now here is where the awkward part begins. This guy i am getting very attracted to…Is this my fault and I should talk to my bf abou it or is it cause I am not getting the emotional satisfaction I need from my bf?
