Men don't understand the whole"need to get my life together right now..no time for a relationship" situation because they handle things differently than we do. He is probably thinking if you really loved and cared about him you would have stayed with him through the stressful times. And he has every right to feel this way. I can see how he fails to understand the situation as it was never explained to him in the beginning. When you finally decided to take the time to explain, it was too little too late (in his mind). It's time to stop explaining the past(which he will never understand anyway) and start focusing on the present by telling him your feelings.... that,although there was a period of time you were apart, your heart was always with him and is still with him. Express your feelings and see if he is willing to give the relationship another chance.
