Combo fed baby refusing breast

Ni

My almost 5 month baby has been bf and formula fed since 2 weeks, I just couldn’t get my supply up enough to ebf. Recently he has been refusing to even try latching except for morning and during the night. He gets hungry and just cries and cries. I try getting the flow going and just kind of shoving it in his mouth but he gets so angry. Then he takes a bottle easily. I’m just so sad, I desperately wanted to ebf for a year and now he’s giving up on it. I don’t really think there are any solutions I’m just bummed out.
