I'm sorry the weekend wasn't so hot. I can't blame the girls in not wanting anything set out that reminds them of the father that walked out on them. It's going to be a difficult holiday season, but you and your family can start new traditions if you set your mind to it.
What is wrong w/your h? He's in crisis. The affair is a fantasy and one that doesn't have responsibility. It is about fun and doing all of the things that he felt he hasn't been able to do since he was a child. It's not about you or your children and that's what hurts. It's all about him and what makes him feel good at the moment. Mlc turns them into the exact opposite of what they were pre-crisis.
It's time that you sought the advice of a lawyer and get something in place for funds to be transferred to you from his paycheck. If you don't, you will continue down this path and he will not provide for the family. I'm sorry to say this, but you have to be the one to step up to the plate and take action on this. You can't rely on him to do the right thing. If he can get away w/o paying you anything, he will. Let me repeat this again for you...you can't rely on him to do the right thing. Please take some time and contact a lawyer and discuss your options as soon as possible.
I understand how you feel, but you have to pick yourself up, dust yourself off and continue moving forward. The feeling of sadness will wash over you, but you have to let it go once the feeling is gone. You will need to take one step at a time, one second at a time for a while. The first order of business is to contact a lawyer and then make a list of other goals that you need to accomplish before the holidays. Take them one by one and do not try to do all of them at the same time.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
