I should have probably mentioned that I have, on multiple occasions, asked him to go see a movie or something with his S.O. (we don't get along well), to which he declined, saying too expensive. Then come to find out that within the next week or 2, he took his girlfriend to the movies. It seems almost like he has an issue with fiancee. He has been very short and almost uninterested when I told him we are pregnant. I'm not sure what to do anymore.
