I save about £500 per month. Should I continue with this despite my wife wanting a divorce?

I'm also unsure of how I am allowed to use my savings during this time and what discretionary spending would be accepted?

I'd like to travel to Australia for 3 weeks but would this be seen as asset stripping?

Can I withdraw money to spend in cash/save?

Can I clear my student loan which I acquired before marriage?

Background:

Dating started 10 years go. Moved in together 7 years ago. Married 4 years ago.
50/50 on all bills via joint account (1K each in every month). Rest of income for discretionary spending or saving.
Mortgage: 150K equity. £120K left to pay.
I have 50K in savings. Partner £2000

Similar incomes and pensions. Partner - spends almost all their left over income income. I save about 1/6 of mine every month and have for many years. No debts between us other than my 6K student loan. No kids.

Unsure if petty to include but wife's parents pay for some of her holidays and her mobile phone bill ...

Rather than fret about this sort of thing it would be better to just get on with a divorce if the marriage is over.

Might seem doom gloom at this moment of time but as david and others have mentioned, There is life after divorce.
Buckle up, accept the fact it’s done and Start the process yourself.
Stop saving, or if you insist use that saving to pay off your personal loans, or take out cash.
You might be able to ring fence your saving prior to marriage.
What you think is fair, the court will usually have a different view

Try to deal with it between you both without the need of solicitors as it can get very expensive quickly.

On another note; my best friend marriage lasted 4 months and she has legal aid and is looking to open court proceeding to settle financials.
I mean what is the point after a marriage of 4 months but who knows.
