Need help

My boyfriend and I have been together on and off for a year and a half and I don’t know what to do anymore. Before it would’ve been him arguing with me constantly when he’s out begging me to come see when he chose going out over me. Then he broke up with me last November because he thought we spent to much time together but afterwards I found out a girl had been all over him the day before he broke up with me but I forgave him because he said it wasn’t anything. Now four months later he chooses going out with his friends over doing something that was planned. What should I do
