Mine told me at one point to find someone else, then told me if I did that we would definitely be getting a divorce. Ignore her crazy. You have the keys in your post. I'm just writing to let you know how sorry I am. So glad that mine is not speaking to me at all (but crazy contacting my kids and bribing me with money). Oh well.
Stay away from women. Most guys seem to fall into that trap quickly. You can't take five kids on a rollercoaster ride. Get the agreement done, get her out of the house, and really work on you, your pain, and your kids.
