What do you think about the perspective of people towards marriage whose parents got divorced?

My boyfriend's parents got divorced when he was a teenager and now he is married to another woman and has a son from his second wife which is common and normal. I knew him for many years and I knew his previous relationship as well. He was insanely very quick to get married to the girl and let her share stories on Instagram as if they were married. (calling themselves husband and wife, this kind of cheesy stuff, and the girl was kind of in search of a husband, so they were ok with the weirdness ) They broke up and we have been dating for 2 months and he already started to talk about this kind of marriage stuff even though I close his way by not responding etc. I know my guy friends are not real fans of marriage and I think it is a very huge responsibility as well. Do you think he has issues with marriage or it is normal for a guy to get into marriage stuff that quick? I think it is unhealthy and don't know what to do. Even though I love him I do not feel happy when he says positive things about our marriage, because 2 months is an unrealistically short period of time to decide to marry.
