What am I exactly?

My boyfriend and I have been together for going on13yrs. We have had a lot of ups and downs. We live about 45m away from each other. He works during the week down near him and I care for my 30yr Adult special needs child in my home 24/7. He lives in part of a friends garage on a cot. I own a home. He comes to see me once a week usually on Friday or sat night about 9pm then he leaves in the morning. ONCE a week. When he gets home after work everyday he takes a shower and usually goes to friends houses. Where other men and women hang out also. (ex-girlfriends included) Or he goes to see his mom or one of his daughters. all are closer to him than me. But you would think if he really loved me like he says he would stick around on the weekends at least and hang out at my house. He never invites me to go run around with him when he is off work or on the weekends. He knows I can usually and he doesn't have to drive me. I have a car. My mom and sister live 5miles away from him also I often go spend a day with them. He never says hey before you go back home come hang with me for the day. Because he never is just sitting in his garage he is always gone just visiting other people. I feel like just a booty call. and I'm tired of it. I am 50yrs old he is 51. I want to have someone who actually enjoys being a part of my life and wants me to be a part of theirs. Not just one night a week at MY house. I don't want to not be open to other possibilities of spending the rest of time on earth with someone who is a REAL part of my life and Me theirs instead of feeling alone. Because yes I guess he is technically my "boyfriend" I am loyal. any advice on what and how to handle this what do you think? and yes I have told him over and over how I feel about things.
