My boyfriend..

So my boyfriend has school all day mon- tues. so those are the days I stay home and go to work. We just bought a brand new puppy together and it’s like having a baby. So I go over and he sleeps till 1pm on Friday, gets up goes to the gym & then to spend time at his old job( he’s a football coach but it’s off season) in which he doesn’t get paid for. Today (Saturday) he sleeps in (I did too, the puppy actually slept which was nice) goes the the store with me to get her dog food, goes to the gym, and now is out at a bar with friends. Tomorrow he will be hungover all day and then I leave Sunday night. Am I being irrational for being mad. He doesn’t even tell me his plans until he’s about to go & he rarely spends time with me anymore. I can’t even go out because our puppy is too little to be left alone and I seriously need a break or some sort of human interaction but I feel like on the weekends when we can spend time together, im always an after thought. I hate just sitting home all the time unless I have work & when the weekend rolls around I just wanna spend time with him but he’s so busy doing whatever. Idk what to do. Advice please, do i tell him my feelings or am I just being irrational
