This is such a classic fixed-sign mismatch! Aquarius and Taurus are both fixed signs, which actually means you're both pretty stubborn about your own pace - his is just slower and yours is faster.

One thing that tends to help: give him a heads up when you're about to think out loud ("just brainstorming, not deciding yet") so he's not trying to process every tangent as a final decision. And ask him for the short version first, details after - fixed signs actually do well with structure, even structure around how you talk.

Worth checking both your Mercury placements too, that governs communication style more directly than the sun sign does.

omg the "thinking out loud vs final decision" thing is so real. my taurus ex used to get so overwhelmed bc he thought every idea I said was a plan we had to commit to lol

following, im the taurus in this exact dynamic and I promise we're not ignoring you we just need a second (or ten) to catch up lol
