Boyfriend says he wants to be back with his ex?

I believe he just agreed because hes tired of me naggin him about beieng with his ex so he just said it in a smart way, b ut it still hurts. He claims he loves me more than anyone from his past but he also states how we fight more than any of his relationships and makes comments as how our relationship isnt as stable and how his past was less stressful basically. Idk what to do, i love him an I feel like our fights are partially because I care more about the little stuff than he does.. Im just heartbroken I wanted to spend the rest of my life with him but on this track.. doesnt look like that will ev er happen. And it hurts from him to compare me to his past.
