Jealous of ex’s success

Newbie here. Please help me model this. In spite of working 2 jobs, I helped my boyfriend at the time, take his business to the next level. I developed and organized his back office for a business he started from scratch. I told him it was just practice for me knowing and proving to myself I can develop my own business when the time comes. His business is now very successful but we are no longer together. I believed I was vested in US but once he started treating me like an employee, our relationship was doomed.
C: Ex keeps getting richer and richer
T: I helped him build that business
F: Jealous, Left out, Desire to get richer than him but probably won’t happen to me
A: starting and stopping and shiny thing buffering
R: another year has passed, no business model of my own started
