I am so very sorry that he's still carrying on the way that he is. However, I am glad that you finally advised your lawyer of the true status of your cancer. She's in your corner and will fight for you the best way that she can. Don't be afraid to share things w/her when you do meet w/her.
As long as you are feeling okay and can take care of your children, then they should stay there w/you. If they aren't w/you, it will create a lot of stress and anxiety for them because they know and love their mom who is having a difficult time.
Your h is always going to find something to complain about because it's the nature of the beast. I know his constant complaining gets to you, but do try to let it go as much as possible. Vge, he could have a pot of gold and he still wouldn't be happy. You could say the sky is blue and he would swear that you are wrong and that it's black. Nothing you say or do at this time will be correct, so you need to let it go. Continue being the wonderful person that you are and let him fester in his sorry little world. He's not happy, but that's not your fault.
They all tell us that we can everything at the beginning, but as time goes by, it's then half and then a third or you'll get nothing. They tell us what we want to hear so that they can escape w/o hearing us beg and/or please. It's their mantra and it changes minute by minute.
As for a job, yes, you do need a job, but w/the chemo, it might be best to wait until you are through the sessions. You don't want to start a job and then have to take a leave of absence because of feeling ill. Your job right now is to take care of YOU. This is the most important fight of your life and your focus and energy has to be on taking care of you.
Vge, God has a way of taking care of things. He may not always give you what you want, but he does provide you w/what you need. Right now, your need is to focus on you and your children. Allow your lawyer to fight for you and to heck w/your h and his selfish self.
Sending you lots of love and positive thoughts today.
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.
