Confused in love?

I love my boyfriend of 15months so much but something not quite right. He quite controlling an not who seems to be something doesn't seem genuine about him. I went to end it lots but he always manages to talk me around and because I love him my sane mind is saying end it as he not genuine but my heart saying maybe he is I'm so confused. I don't feel I make any right decisions my marriage of 9 years ended 3 years ago and everyone when they see us together say we still in love with each other and I do have feelings for him but we ended as I couldn't trust him, as he cheated. I had another serious relationship was totallyl in love with him he cheated but then said made mistake and wanted to marry me. I don't feel I can trust men or I choose really badly but have feelings for all 3 men? I love my boyfriend would never cheat on him but I feel if I can have feelings for these other two men how can he be the one? My mind feels so confused totally what do I do?
