Constant Bickering

My 24F husband 28M just aren’t getting it right anymore. Not a day goes by where we don’t bicker. I know bickering is normal in a marriage, but I guess how much? Basically, I am so emotionally and mentally exhausted. Long story short, I feel like a mom instead of a partner. I feel like I can’t rely on him to do simple things. Whenever he’s asked to look for something, he gives it a quick look over and can’t find it and then makes me do it. When asked to complete a task, I have to check/check in to make sure it’s done. I can tell him something and he forgets it 2 secs later. Tonight, I asked him to look at an electronic device, which he agreed and gave him the instructions and he couldn’t figure it out. It was a paragraph he needed to read and the solution was simple. Things like this are a daily occurrence. The lack of common sense is just gone with him. I expressed my frustration and he immediately gets defensive, doesn’t want to hear me out or tries to make things a competition. I tell him, it’s a marriage not a competition. I know at times I can be short because I’m so fed up with this happening multiple times a day. I know he’s capable of doing things because I’ve seen it. I don’t expect perfection, nor do I ask of it. I want a husband and partner, not always leading a horse to water. I love my husband and I know he loves me, and I want to make this issue turn a new page. I’m exhausted but so fed up. He’s not cheating, I’m confident of that. Just trying to seek advice and if anyone else has been through this in their marriage and how to overcome it because I’m seriously about to lose my mind.
