Sounds like he's making excuses to see you- that is a good thing. Do you have a legal separation agreement in place? You might want to look into that- it will protect you and give you what you need financially. Or if you guys are friendly and you think you can negotiate without a lawyer- I would just ask him for the money. Bottom line though, if you pull back from him more it might help him realize that he may lose you and motivate him towards your R. Have you considered going dark on him more? Does he know that other men may be interested in you and that you don't "need" him anymore?
