Boyfriend is stressing me out

I need to vent…
Out of nowhere on Monday, my boyfriend of four years got very angry at me for putting make-up on. He refused to talk to me the entire day, and we even missed his friend’s party because he would not get out of bed. Every couple of hours I would visit him and ask if we could talk, and he would either ignore me or say nothing was wrong. At the end of the day, I went home because it was getting late and I asked him one more time what was wrong, he just said nothing and refused to get up and say goodbye. As I was driving away, he texted me saying he is not going to my cousin’s wedding. The next day he said he was not mad at me for putting makeup on, but he was just tired. He keeps repeating that I abandoned him, and we should have talked but I stormed out. He made it seem like he did nothing wrong all day and ignored the fact that I tried to communicate with him the entire day.
He does not want to go to the wedding because he is afraid that I will abandon him again. Over the past few days, he keeps bringing up things I have done in the past and how they hurt him. Some of this stuff happened 4 years ago and I am still unforgiven.
We are at the point now, that he is going to the wedding, but that is hanging by a string. I feel like he could cancel at any minute. He is very miserable about going. I do not want him to come because he is stressing me out and I am so worried that anything I do will make him feel like I am abandoning him. I just want to enjoy my weekend. I haven’t seen most of my family in over a year. However, the only reason that I am pushing for him to come is that I would be so embarrassed to show up alone after my family was looking forward to seeing him. He seems to always skip out on family activities. My family would be disappointed, and I feel rude towards my cousin who spent money on my boyfriend to be at his wedding.
