Realised I am in love with my ex but its too late

Warning : My english is bad. So here goes : Me and my ex started dating in January 2013 and ended in march 2013 so it was not really a relationship . We both didn't love each other then . It was mostly physical. One day I found out through his best friend that he was cheating on me with one of his ex ...I asked him about if that's true but he denied everything and asked me to trust him . He said he never want to lose me . But we weren't dating for a long time so I decided to break up with him . He kept calling me and texting me for a month or so but I said "I never want to see you again ". Initially everything was fine because I was sure I didn't have anything more than liking for him but then I started missing him more and more and it got worse ..I realized how important he was in my life and that I never felt the way I did with him . I dated two guys after him but he was always in my mind so I broke up with them . I am currently single ..I want to tell him how I feel about him but I don't know how to do that .....its been more than a year. Please help me

Go and approach him. U will never know wht he thinks about u untill u talk to him.

I agree life is too short approach him ......good luck
