what do i do after an argument with my boyfriend

we live together and have 2 kids together and he never seems to want to take the time of day to play with our daughter or to just sit down and watch tv, but instead he plays video games all day and doesn't listen to me when i need help with our 2 kids or even when our daughter is at his feet asking him to carry her. so he did this yesterday and i had it with him doing this all the time so we began to argue. then the time went by and he finally said sorry.only to tell me he was leaving to a friends house to party.
