exboyfriend is bipolar

I am going through the same issue right now..writing this while in tears! i feel helples! He broke up with me 4 days ago saying he doesn't feel the same for me anymore and its been bothering him. we were together for 7 months and for 6 months we were so in love and things couldn't be better in our lives...we were like the perfect couple..he had wanted me to move in. The one night, 5 days ago, he was telling me that he loved me but he felt differently, and that somedays he's so in love with me and can't picture his life without me and somedays he just wants to be by himself...and he doesn't want to break up with me though....then the next day he calls me and says he thinks we should just go our seperate ways....i was so completely heartbroken,,,,we shared so much, he was my best friend. I'm so devastated and hurt. He was diagnosed when he was 9yrs old, in therapy and taking meds for a while, but then a few years ago stopped all of it....he said he could control it himself and knows how to handle things when he feels like he's getting into one of his moods...i love him so much and i'm so sad i can barely type right now due to my eyes clouding up with tears...it was so real for me, but i keep questioning,,,did he even love me or did he just think he did?,,,i'm so hurt, upset, and confused.

is he gonna change his mind about breaking up with me? What should i expect?
