Sounds like you're off to a good start.

Wise move!

but don't know how she can see my improvements without seeing me?


Really doesn't matter. You might not want to hear this, but seeing your improvements may or may not make a difference to her...especially right now when her focus is elsewhere. Make substantial changes for yourself so that you grow stronger and more independent as an individual. That will benefit you regardless.

I took very good care of her financially and seems to, now, resent all the material things I bought her, which in hindsight was a mistake.


I wouldn't get caught up in this. Believe nothing she says...she doesn't even know what she wants or really thinks right now.

We should of travelled more and spent less on petty things, but I've acknowledged that and intend to change.


Shoulda/coulda/woulda. Did she make this clear to you and did you simply ignore her? Did she come to you and say, "Let's stop spending money on XYZ and let's travel more? Perhaps that's a point of contention, but it's probably not a real issue. People with a good relationship bring up things like that and make new decisions together. So, again, if you were ignoring her on this when she was telling you what she wanted, then THAT might be an issue to consider. If she wasn't, and she's just using it against you now, go back to believing nothing she says and simply focus on you and building a good life for yourself.

Maybe too little to late


Maybe, maybe not. The key is to focus on what you can control (yourself and building a great life) and truly accept that this is her choice and there's not necessarily any one thing you can do to "get" her to want to come back. She has to come to that conclusion on her own. Your best bet is to build a great life for yourself as a strong, happy individual.

Best wishes.
