Thank you for writing.
You may be jumping the gun as you haven't yet separated from your wife. Take your time. As to whether you can attract another woman - we can't say. We can't discuss your financial situation, we don't know it. Your financial situation, unless dire, shouldn't impact a new relationship but it sounds like you think money will attract a "younger" woman? I'm not sure what you are looking for in a new woman other than her youth and sex. I think these are questions you should be asking yourself rather than someone else. Self-reflection and mindful thinking about your situation sounds like a good idea.
