Ex boyfriend

Hi just wanting some advice, my ex boyfriend as of Saturday has Aspergers and out of no where decided to end things on Saturday he did it via text which I was shocked. When arrived home to told me his concerns and that he can't see him having a family etc.  He has a stressful job and struggles with it sometimes.  we moved in together 10weeks ago I moved cities for his job and moved my life for him.  I just don't know if it's worth trying to work things out with him, as we go on holiday tomorrow and every time he see me he cries I just don't know what to think.
