<human>: Can you succinctly summarize the text in 1-3 sentences?

It might sound silly, but my boyfriend is a social butterfly and when we go out he tends to be all over the place and too drunk. Prior to the event, I told him, that it was important for me that at least, he would be there to kiss me at midnight because it is our first NYE together despite being together since 3 years. 

When the countdown came, he was not there. I am very upset for this and told him and an hour ago I found a picture of him with his ex-girlfriend on Facebook at midnight and other friends. I want to know what to do!
<bot>: Boyfriend was not there to kiss me at midnight despite a promise and was with his ex-gf. Also, he is upset at me because I am upset at him? What can I do?
