The house sounds like a financial anchor and I can understand you going through some phases of anger now. Your STBXW has really thrown a monkey wrench into your daughters and your life.
But I see optimism that you know that your life will move on and you will make it better.
Just make sure you have closure on your M and emotions before letting a relationship build too much through friendship. A 31 year old woman is in her sexual prime and may be wanting things to heat up a bit quicker than you are really ready for. Some passion too early can cause for some serious judgement errors.
