To the original poster: If you do decide to re-engage this relative and resume the relationship, PM me and I can direct you to a couple of resources where you can find others in similar relationships. It helps tremendously to learn that you're not alone and that others have faced the same dilemma. Part of the reason why consanguine romance can be devastating is the fact that you can't realistically talk it over with a close friend or loved one. This kind of relationship puts us down at the level of pedophilia and bestiality in many people's eyes. They want to see us locked up rather than provide emotional support.

Regarding the poster above, I agree that you need to unblock your new relative and at least give them closure or an explanation. They are HURTING right now and at a minimum they need to know what's going on.
