I have been following along on your thread. (Thanks very much for stopping by my thread today. It cheered me up.) I'm so sorry that you are having to deal with this. I think that I speak for everyone here when I say that this isn't fair to you.
Your business situation sounds like a nightmare, but you are navigating your way through this with grace and intelligence. Your friend sounds like a Godsend (I mean that literally),..........so if God knew what you were going to need at this time in your life, trust in him to provide for you over the next several months.
Mila, I haven't seen anyone here ask you this yet, and maybe I missed this earlier, but have you consulted an attorney to get information about what kind of legal agreements could be drawn up to protect you and your daughter in this situation? In my part of the country a consultation costs around $250-$400.............probably more in California, but this info will help you plan........and at least in my situation, our legal documents actually protected us from angry interactions. I truly believe that our pre-nup and my Herculean effort to be civil (H/XH also worked at civility) kept our situation from spiraling downward................By way of example, I have a co-worker (woman our age) who wanted a D because H has major anger issues. Their D was final within 2 1/2 months (no kids) but it was drawn up by a paralegal and they still hadn't sold their home. 8 months later, her XH is still living in their home (has a GF staying over), my friend is paying half of their mortgage but has been living with relatives this whole time, and they haven't yet had one showing by a real estate agent. She is now spending a lot of money on an attorney and court time to protect her investment (home). ..................Having appropriate legal documents early in the process will protect you now and in the future, may keep this situation from spiraling downward therefore leaving open the possibility of reconciliation in the future,...and may even jar H into reality a bit.
