Getting involved when there is an expiration date

[Anonymous]

This may be not it at all, but is it also possible that by saying that he could be moving to his home city, he is kind of giving himself a potential out? This happened to my sister, the guy actually pretended he was moving back to his home country, instead of breaking up with her the usual way. I'm sure this isn't happening here, but he may have partly brought it up to deflect your want of long-term commitment?
