I hate to say this, but its just being realistic...
I imagine at first life with the OP is wonderful. I mean it would HAVE to be for them to continue in that relationship. I can only guess, but just examining my own sitch, I know they go out a LOT. WAY more than we ever did these last few years. Then again, when you don't care about the financial repercussions and just do what "feels" good EVENTUALLY there will be consequences. So I imagine at first the thrill is quite exciting. A NEW flirtatious R, lots of fun, new and exciting things. Honestly it has to be quite a rush. But when things settle down and become "routine", and the bills start coming in, and there is no more cash or credit left to do those fun exciting things anymore and the reality finally hits home-I think THAT is the point which a lot of MLCers finally realize they have just traded one set of problems for another, only in most cases since the affair is an affair DOWN, they realize just how destructive their actions had been. What they choose to do about that situation is then ultimately up to them, or is some cases, up to the LBS.
