I dont feel like a wife 🙁

Let me start off by saying that we have been married for three weeks now. This weekend we were supposed to go to a resort as a pre-honeymoon which we haven't taken.
Long story short my mom has a sprained ankle and his uncle is in a hospice because they gave him only days to live we decided to cancel the resort and have our own plans but that didn't happen due to the fact that his uncle is in hospice. His little brother also decided to come to town due to the fact of his uncles health I decided to cancel our plans due to the fact that family is coming from out-of-state because of his uncle and we weren't going to hang out so I decided to take care of my mom which cannot be alone but I came to find out that he was hanging out last night with his cousins and he decided to come home at three in the morning. 
I have no problem with him having a social life is own that is very healthy to me in a relationship but I just feel left out because this is the first time that he hung out and I wasn't included neither was I included in his plans nonetheless that we were supposed to hang out and I had canceled because I thought that it was not appropriate but here he is hanging out.
I just feel left out and I assumed that when we were married we would do more's things together ☹️
I would like to tell him how I feel but I don't know exactly what I should say any opinions advice I would appreciate it
