Citizenship application

I worked in Germany with a blue card for five years and three months. This December I applied for citizenship but even though I have the unlimited work contract, we agreed with my employer for me to leave end of January after some compensation. They wanted me to leave but I fought back since there was no valid reason. My husband is EU citizen and he has enough income to support us.How would this affect my citizenship application? I also applied  permanent residency but I haven’t received the card yet. I only have fiktion document  valid until 2027. Meanwhile, he got a very good job offer in Spain and he will start in March. I will stay in Germany until I receive my citizenship hopefully. I’m doing an online master degree right now.Is there something I need to be careful about? He can have German work contract for a while but he wants to switch to Spanish contract since it’s more beneficial. Thank you.
