ex boyfriend / babys father problems

eden
is it okay to ask the babys dad/ ex boyfriend to help with purchasing a few big items for the baby? he says hes going to also have to buy the same items. the baby will be with me majority of the time and its his fault that we rnt together so in my mind i think its only fair to help out with a little since the pregnancy is a full time job for me and i did the whole baby shower by myself and he only helps out when its convenient for him like dr appointments.
