I feel like I’m a single parent

My husband choose to take part time tuition for students until 10pm over accompanying me during my pregnancy and now the baby is still young and he wants to take one more year because the student is taking national level exam. Do I call him irresponsible? My in-laws also never take care of the baby for one day, and insisted that they are old already and have no time (they work barely half of the week). My own mother cared for me and the baby for 6 months singlehanded with no resting day and my husband still got much to complain about her so he even stayed back to parents place for the time being. Now my husband just hired a maid and do the bare minimum himself. Weekend he would choose to watch videos over playing with the baby too. Is it common for husband to do this? Is children really the tomb of marriage? (By the way I’m too working full time, just work from home thank God) #advicepls
