Bf trouble.

I'm 16 and my bf is 17. Today my dad had a heart attack and I was really upset about it and my boyfriend was with me when I found out. He took me home and I asked him to stay the night with me cause I was really upset. He had plans to go drink with his mates and when I asked him he threw a big turn because he couldn't go with them. He told me he only wanted to go home so that he was at home. Even when I told him that I really needed him for support tonight. He ended up by saying that he would stay but he's been rude to me all night since then. While I was in the shower he was messaging his mates saying that he wishes he was with them instead. I'm really upset by this cause I thought that by being his gf that when I need him he would be there for me. Do I have the right to be upset with him or am I just being a bitch to him.
