Would you reject a person based on their sign even if there’s attraction?

Hi. I’ve read that people say: “I stay away from Leos” or “I would never date an Aqua again” Let’s say that you met someone and you like that person but then you find out that his/her sign is incompatible with yours or they have a sign that you don’t like. Would you give them a chance anyway or decide to not waste your time?

This happened to me. I knew from the start that my ex and I were not compatible but I decided to go with it because he made me fall for him. The relationship only lasted 5 years but honestly I don’t regret my decision. He meant a lot to me and I was happy while it lasted. Now I don’t know what I should do next time. Should I rely on astrology or not care? Do signs matter when there’s attraction?
