He loves me? He loves me not? Should I block him?

He barely calls and claims he’s tired all the time. I put forth more effort in trying to see him but always fail on “my terms.” And when he asks to spend time with me and my two kids, I tell him “no” on his terms. We text/talk maybe once a week or two. We are planning to marry some time next year. I’m just tired of me putting forth all the effort in trying to see him and doing things for him, and he never puts forth any effort to fulfill my requests of him. I take him lunch to his job that I personally cook, and anything he (used to) ask of me I would do. For the past couple months I have purposely made myself not-so available to him. But I still am not winning. I blocked his number yesterday as a result of him not attempting to return my calls or messages on Thanksgiving. I even went by his grandma’s house after spending holiday with my family and he was not there. He did not answer his phone or return my messages. He says he loves me and there is no one else. I’m so over the back and forth with this. I try to keep busy doing other things but I still have him on my mind. I do not call and text him everyday, and neither does he. I’m keeping him blocked indefinitely until he goes over and beyond his efforts to keep me in his life. I used to push for us to be married soon. But I have backed off. He still has not stepped up to the plate. What to do?
