Too much or bare minimum

At this point in my relationship I feel crazy. We’ve been/lived together nearly 10 yrs we have a 2 yr old son. He works I stay home bc that’s what was needed to work for us. He spends a max 1-2 hrs w our son when he comes home from work but it’s un-engaging and for the most part seems like he’s being forced to interact. When I’m trying to direct or discipline our son around or near him & little man isn’t being very cooperative he does nothing to help me out even when it’s made clear that it’s needed. More often than not he will have him get his iPad to sit on the bed to watch tv and then he’ll 9/10 fall asleep. On days he has off work hes most likely made plans for side work or he wants to sleep and when he does wake up he’s checked out and gets on his pc. Doesn’t help me enforce bath and eating a majority of the time.

Sometimes I really sit up late wondering why we’re together and I know One main reason I stay is bc our son adores his father and his whole life lights up before your eyes when he sees him. But for what else? He doesn’t seem to be there for me emotionally but expects me to be all in sexually.

There is seriously so much to unpack here - am I asking too much from the working man or is he doing the bare minimum?
