Moving to Finland with wife

Hello, We are a EU COUPLE citizen couple currently living in Estonia. I'm mid level software engineer working in tech and she has her own remote business as a self employed. We have decided to go to Finland for personal reason, and since my company is also based in Finland, I can just switch contract

Since my contract goes from Estonia to Finland, I will temporary have the same salary wich is 3k5 But my wife doesnt have "contract" business, meaning her income depend on customer and not based on some contract with other company. So the income can not be verified like a freelance contract.

The tricky situation is that we firt came in Finland a year ago as both self employed, I applied to migri and got rejected because I didnt had >>finnish<< self employment and permanent b2b contract... And she also got a medical emergency giving her a temporary code

My question is then the following Can my girlfriend get registration with me as a cohabitation partner (we Have proof that we have lived together for at least 2 years) And we will not end up in a situation where I need to move first, she will then need to beg to get residency
