2nd pillar and divorce

I am married in “separation of property”.
Found out that my ex wasn’t working or making any money during 1 year of your marriage (she has a decent paying job) when we did our tax return. Basically she made a fucking 16k and most of that is from another job at the end of the year. She was also contributing to another pension system outside of Switzerland.

Meanwhile I was making over 150k year after year.

We have been married since a few years and I did buy backs from my personal money because I was self employed (around 30k) and I had a plan paying the highest contributions.

How fucked is my pension? I read somewhere here that buybacks are split in the matrimonial system and others are saying no.

I honestly regret having a 2nd pillar while I was self employed. Should have maxed out my 3a where I get 15% performs these past years.
