Taken for granted

Why do we get taken for granted? Like i do everything for my son. My boyfriend keeps threatening suicide because we fought about him being selfish. but I'm the bad one. The unfit parent. His mom wants to take my son away from me!! But who is sitting here with him while he cries? Who nurses him? Who gives him his baths? Tummy time? Me!!! He changes the night diapers when i ask. Other than that i change him. I take him to the doctors.
