Advice please :(

Okay, so this will be long I will try to sum it up the best I can. So basically my boyfriend and I live about 1.5 hours apart, we both have a good job and I'm in school too. I have a toddler from previous relationship(I was single for over 3 years and a single parent) and he has 4 kids. We have a baby together, due in may. I only see him about twice a week and that's for about 4 hours each time. I am starting to resent him and get angry because every moment of my spare time I am cleaning and organizing for new baby coming and I still feel like a single parent. He has done nothing to his home to prepare and he spends all his extra time at basketball games (and other sports) and practices (even when it's not his time) I have no issue with him supporting his children and spending time with his kids, I encourage it, I am not being petty with that, that's one thing that made me love him so much, but I feel like me and my kid (s) are neglected in a way and I want my kid (our kid) taken care of too. He chose to have another family in another state and i feel like he needs to divide and provide equal time. He fills me full of hope and promises that things will change and he will be around more but each week is the same. I don't expect him to provide for my toddler and we don't share money, time and support is all I want. Am I being over emotional?
