No idea why my husband does this?

I don’t know why my husband hides his money from me? I mean we both work, he buys me stuff whenever i need something even as a gift he will surprise with things. He does most of the spending at home, bills and everything. But I dnt know why he doesn’t tell me how much he has or how much savings he has?? He lies and ‘fake calls’ his friend to lend him money when i know that it’s a bait lie.. but why does he do that in front of me???
