I understand feeling hurt in this kind of situation, but try not to see it as a betrayal. It could very well be that when you joined them, the FW had every intention of things working out and this being her path in life. Unfortunately, it is not until we are living in it 110% that we realize, maybe we were wrong and we do not have what it takes to commit to the path in front of us. I know that makes things hard for the SW, but I assure you, it is just as (if not harder) on the FW in these cases as she will often feel like a failure or like she has let everyone down. I hate it when these kinds of stories come up and everyone seems to run to the aid of the SW and villian-ize the FW. Not that anyone is doing that in this situation..Just saying that it is hard and sad, but try to go easy on the FW. Very rarely is she someone that has set all this up on purpose just to destroy the others involved. I pray that everything works out for you guys. PM can be such a blessing.
