You have already commented on her new job via text and in person.
You certainly exhibited support when you agreed to help her financially.
It is really hard to understand why you would even want to send this. You W knows you love her and want her back. She knows you will not set boundaries with her. She knows you are an available option yet has not pursued any sort of R w/you other than very casual friendship and co-parenting. While this may hurt she didn't even acknowledge you when you suggested you and her try one of the restaurants she likes to eat at w/her friends.
You never really addressed my post y'day. When you go down/worried/nervous about one thing (in this case a job) you seem to cling to your W even more. It is a pattern and not a good one IMO.
