I don't know how much of my situation you've read, but my wife will finish a degree program in June that will enable her to make a good deal more money than she currently is. In theory, we would have a realistic option for splitting up then. Whether or not that will come to pass, who knows.
I can’t stress this enough - do not initiate divorce yet.
You need to wait it out. Let her text OM, let her simmer away…. But don’t push her, set ultimatums or lose control of your emotions.
You need to wait until she has finished her degree in June. And then go out of your way to help get her a well paid, full time job.
Once that’s done, then you can consider pulling the rip cord.
I don’t know what country you’re in, but regardless, if you wait until she has a degree and well paid job - you could be hundreds of thousands or even millions of dollars better off in a financial divorce settlement.
