Love / Does Polish guy hide his divorce usually? [7]

I have talking with a Polish guy around 1 year, during that time I have asked about him once that does he have any relationships before, he said he have a 5 years relationship, once I asked why he broke up and he only said his ex. After we in relationship to 2 months, he suddenly told me that he is divorced, and there is 3 yeras relationship with 2 years marriage. I am shocked, because I have mentioned his ex few times before, he never said that is his ex-wife, I always thought that who is his ex-gf.

Is it normal that Polish will tell this after in relationship?
