How do I get my SO to listen instead of "fix"?

Hi Rachel! Would love some advice. I love my SO to pieces, and he's wonderful, but something has been grating on me lately. Sometimes, when I'm frustrated with something that has nothing to do with him, he has the tendency to try to immediately fix whatever problem I'm having. It's admittedly helpful sometimes, but, other times I'm so exhausted with said problem that him suggesting a fix just makes me even more overwhelmed. Plus, I don't always agree with his POV, and if I don't immediately accept his advice, I feel like I'm doing something wrong.

I am sympathetic to him, because sometimes I do want advice, and other times I don't. So how do I solve this without confusing or offending him?
