I know my boyfriend since i was a kid, we seen each other on and of for the past 6 years and last year we finally got together properly. For the first few months everything was fine, until he would break up with me and ignore me for a couple of days,then he come to me and say sorry and that he does love me. this happened a couple of times until he told me he suffers from depression and just has to be on his own sometimes. So that was fine, i understood. We moved to canada to work 5 months , and begin living together when i really seen a different side to him. When hes nice, he is the best, like buying me chocolate taken me for dinner, treating me like a princess, hes very protective of me in a nice way. Then, he'll take a mood swing and turn into a different person and yell at me and everything is my fault always, he wont talk to me for about 3 days, and then he'l be normal again. This keeps happening. Iv tried to talk to him and he has admitted that he does become a different person and said he cant help it and he cant help the way he treats me. He also cant handle stress and gets stressed all the time over silly things, like oweing me money for bills or if he thinks hes late for work he wil be so hatefull to me. I looked into Bipolar symptoms and talked to him about it, he said he does have racing taughts, he thinks about sucide and knows exactly how hed do it. but said he never will. He always have an very,very high sex drive and says he needs sex al the time!Out of the blue he will get up and start tidying the house, or if were relaxing watching tv he'll get up and say lets go out, he gets tons of energy out of nowere. He is happiest when hes working. He does love me, and we have our furture planned out together. But when he takes a mood swing i am the only one that sees it, he is so normal with our friends and with me when our friends is around. I dont know what to do because he wont go to a doctor. This morning he was dropping me to work and told me to get out of the car to f**k and to f**k of im nothing but a b******d.That he doesnt love me. I told him to take me home so we can talk and he wouldnt talk to me, he drove home.. he got out of the car and through his keys on the ground, yelling at me and being so hatefull. I picked up the keys and he asked me for them and i said no, not until you talk to me, he grabed my laptop and said if i dont give them to him hes going to smash it. I have never ever seen him act this bad before and im scared of what he will do. I just dont get it, hes so normal with me until he takes a mood swing. I dont know what to do
