help!! is this "break" worth it..

Recently my boyfriend of 4 years says he wants to get his life together speaking that I mainly support him through everything. He also threw in the fact that he hasn't spent time with his son bcs all the time we are together.. I love his son like my own but the thing is when we have him and it gets dark he wants to go back with his mom.. and crys and we do not know what to do. Other then that his mom never replies when we can get him even though we are on child support for him. His mother isn't very good at communication. I have told my SO to try harder to get him but he doesn't. And when he does have his son I pay more attention to him than his dad. I feel like his point isn't valid bcs I always say hey let's go get him or take him here and he says no. Is this break work it or it is a fake break.. recently I saw a hotel charge and a movie theater charge and he has never payed for us to attend the movies. I always do.. what do I do what do I say..
