People do change, to be sure. It's more of a "process" rather than something that happens quickly...so the question...is seven months enough time? I don't claim to know.

What has changed since your breakup? You said it was caused by your moving away...have you moved back? Do you see some special irresistible attraction to this person? Obviously you already know that the relationship will be a bumpy ride, but it is truly your decision to make.

Tell your family, and make it short and sweet. If things go well for you, they will change their opinion. If things DON'T go well....BUMMER!
