How would you take this? Am I overreacting?

Okay so we’ve been together for going on 6 years. I’ve been (arranged) married once he’s been married twice. I love him and he knows I want to marry and when his friends or even my family brings it up he always says he’ll nah “jokingly” or maybe one day and one day he even told our friends when we get married I want etc at our wedding and to me in private he says I do want to marry you maybe one day or who said I didn’t want to marry you or I've been married twice. Like he has all different kinds of responses. But today I asked him hey babe have I failed you do you not want to marry me. His response today was I just have to make sure you’re the right one. I don't know why but that broke me. Did I over react? Mind you he put me through hell for a whole year 2 years ago and still I stood by his side and yet I’m sure I want to marry him. And we bought a house together and have lived together for 4 years.
