Need some advice about two residence permits (from Poland and Belgium)

I'm junior IT specialist.I currently live in Poland with my wife who is a Polish citizen.We want to move to Belgium (Antwerp) with my wife and save some money to put the project into effect (Search Engine optimization company) I hold a Polish permanent residence card, (not eu long term) can I apply for a Belgian residence permit based on marriage with EU citizen and is it possible to hold the two residence permits at the same time?

To be honest due to living expenses and expensive houses we want to move back to Poland after 3-4 years but I would not like to begin whole process again for residence card... If I get Belgian temporary residence card my polish permament card will be revoked? If yes may I apply eu long term eu residence based on marriage? I have seen the act but it's not clear. I do not have stable income that means I'm not allowed to apply although I fill the all other conditions?

I appreciate your help

I would not think it very likely. From what you are saying you are not an EU citizen and hold a Polish permanent residence card. How can you then hold a Belgium residence permit at the same time? You cannot be resident in 2 different countries.

its possible to get residence card from Belguim, but prior that your wife she need to get a job full time, once she will have residence card then you can apply as family member.

Thank you for info

May I get a long-term eu residence based on marriage with a Polish citizen? Because there is an act which says ''has health insurance'' and ''has maintained a stable and regular source of income''

I have a stable income but I have not worked for a Polish company and also I did not have any time a health insurance.
