okay i've been suspecting that my on and off boyfriend of 5 years is bipolar. I care about him and love him deeply. At times he can be the nicest guy to me but there are times he starts a fight for no reason. He will do something on purpose, so that i will get mad, and then starts the arguments. He told me one time that he starts kidding around with me and I will argue back with him, It gets in his head, he would forget that he was kidding around with me actually will get mad for no reason. He's not the nicest person to his mother or his sister. Him and his dad aren't that close neither. I know when he was little his dad would always make comments about his weight, because he was chunky, He would make fun of him and call him names. I know that did scare him. Sometimes i get tired of it and want to leave him then he'll start crying and get emotional and say he wont pick a fights just because. We are sexually active and we have sex about everyday. So his sex drive is pretty high. Also his sleeping patters are kinda weird. He will got to sleep late wake up early and take naps in the late afternoon. Sometimes if he doesnt he gets irritated easily and gets mad. When ever we do take a break he wouldnt eat. He only eats like once a day. He would also abuse drugs and alchoal.But now that were back together he will eat 3-4 times a day and doesnt do drugs and cut down on drinking. I'm not sure what this all means or if im just over reacting but it can stress me out so any answers????
