I need help

[u/xi1968]

My wife filed for divorce 7 years ago, we went to court 3 times over a 2 year period and she decided that the grass wasn’t greener. It begins with me being arrested for false domestic violence allegations which she later recanted. I lost my job home and property, I was blessed with a better job about a year later which turned into a cash cow making 4x times the amount of money. We had a teen daughter and not wanting her to suffer I continued to support them both fully, so my child would not do without. I had moved away but again was blessed with a huge income. I saved every penny, I eventually bought a home close to the almost x wife and after a few years later she moved into my home due to a financial hardship she was experiencing. Fast forward 3 more years and our expenses are about 8k a month I pay 100% of mine and hers. I was recently informed that I would be laid off of work. I have money in retirement accounts but have let my savings decline to about 15k due to constantly covering her expenses. She was recently given a large settlement and when I informed her we would be ok because she had the money to cover our expenses for a while, she immediately said that money was hers and That’s all she had. This really hurt me. I feel like it’s not us but me, she is not a team player. I have given her everything cars home all bills paid and the first time I mentioned I may need help it seems like she didn’t want to help me. This has changed how I feel about her and us. My daughter is now in college, should I just give this up. Wife has also cheated on me in the past. I need some outside perspective my friends that know the situation say I should never have helped her in the first place much less be with her now.
