Getting reinstated just so you don't have to explain to a date why your family doesn't have anything to do with you seems to be a very silly thing indeed. In my mind you'd have more to explain about why you have to pretend to be a JW when around your family. I'm sure you'll find that there are plenty of girls that will love that they won't have to worry about meeting your parents and dealing with in-laws down the road.
You'll probably also get more respect for having integrity in spite of the fact that it comes at the cost of your family. It's part of what makes you you and what makes you an interesting person. Everyone has a past, it's not your fault you were (presumably) born into a cult. It's not shameful that you were in a cult, it's remarkable that you escaped.
What's more is that exJWs don't have a monopoly on estranged families. It happens all the time. You're not that unrelatable, and chances are you'll find many who have a either experienced strained relationships, or know others who have, due to religion. Maybe not as extreme, but your situation is far from unique.
