Good question. I would assume not. If remarrying is off the table, I would think sex outside of marriage would be a big no no too...
I don't want to get into a religion discussion, but I will say this. I think it is silly to deprive yourself of having a happy, healthy relationship in the future based on some ancient scripture. I'm Christian myself, and I believe God wants us to be happy. He gave us free will, and with that comes mistakes. It doesn't seem right to be forced to lived a single life because of a bad choices made by either individual in the relationship. You can't force someone to be with you either. So if they up and leave and you've done nothing wrong, you're doomed to a single existence. I'm not down with that, and I don't think God is either. Not telling anyone what to do, just my 2 cents...
