Lonely I guess

I don't know if I have a right to feel lonely. My boyfriend works 15 hours a day and gets one day off a week. He dosent even see our baby anymore. He leaves before he wakes up and comes home after he is in bed for the night. I ask if he can please just maybe eat dinner with me one night or help with the baby, but he dosent. I know he is working hard but I guess I am just lonely.
