Interesting thread... I'm recently separated from my wife and partner of 10 years (the only one I have ever had). I love her and tried all I could to fix things, but it the end she choose what she did... (I'm not blameless in it all, just more hopeful to fix it than her it seems).
Anyhow, point is yes there are soul ties, yes it hurts, yes I believe it is not God's will for marriage to break, but as it says in scripture we are weak... and have free will to mess things up with.
Through it all though I know that for me God has been there and is my strength and hope for the future, when I needed him the most he gave me ways out and the support from various random sources when I needed it. It the connection I have to her is to break it will be though God.
I pray for my wife and hope she comes back to the lord... but as it is she doesn't want that.
