For some reason I don’t have any pressure in my bathtub cold water side but the hot water runs wide open any idea why I’m not getting hardly any pressure to my cold water side? It’s separate handle not one handle
I suspect some debris got into the line during this breakage or subsequent fix. This debris is now lodged behind the inlet side of this faucet restricting the flow. No easy answers. You just have to dig into the situation. Either find and get rid of restriction or replace faucet. Once you have the line open make sure that you flush the line well. Once is enough.
