As an Aquarius I dated a Capricorn, the situation became highly toxic from the start (he was full of insecurities and it made him controlling, and I let it happen instead of ending the relationship right then and there). Thankfully when I said I wanted to end it after 2,5 years, it ended amicably and we did keep talking as friends for the next 2 years. That worked for us, the relationship didn't 😅
