You HAVE TO let her leave if she wants to, don't try to hold her back, it will only make her pull away harder and quicker.
Does she work? Either way, protect YOUR money and let her deal with hers. She will resent you if you control it all/cut her off, and she will empty the bank if you don't control enough.
Concentrate on you and your D.
M: A really long time. Crisis: 5 years. She's still worth it.
Life is never made unbearable by circumstances, but only by lack of meaning and purpose. -Viktor Frankl
