If your affair turns into a legitimate relationship, the two of you have to seriously talk about the future and figure out if you both are willing to split up your families. At this point, there is a lot at stake and you both must think long and hard about it. You and your lover must go to a lawyer together and get advice. It’s imperative your lover comes with you. If they aren’t willing to go now, they won’t ever make a real commitment to you any time later on. You need to make sure your lover is, at all times, just as serious as you are about where your relationship is going, if you plan on ending your marriage.
