I'm sorry that he didn't follow thru on the allowance. Well, that leaves you no choice but to use the joint account where the mortgage is setting. I do hope that you can get some of your legal issues resolved and finally get some support money in your account.
I'm glad to read that his family came out and everyone had a great time. All of you needed to sit down and have a chat and it sounds like they do understand and are being very supportive. Ambivalent, please do not hesitate to ask them for help. They've offered to help you...use them when you need support and/or assistance. They are family to you.
I do hope that you are feeling better and stronger as each day passes. It's not easy dealing w/the mlcer and the finances when they do not want to sit down and discuss things, be rather would prefer to communicate via text.
Take care of yourself.
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.
