Luckypenny, you have my sympathy as well. I am so sorry it happened but it was inevitable. I know it is a very hard decision to make but it would make you happier at the end knowing that both girls are happy living seperately.
See it as a marriage that just can't work. These two need to be seperate.
I see this as you being the child in a bad marriage (mine actually) and as much as it hurts to see them seperate, in the long run they will be happier and so will you.
Can you imagine living every day not knowing when the next fight happens, and will it be fatal..??
This is never easy, especially knowing how much you love these guys..
