My feeling is you should forget him and move on. It’s not just his sun sign, other aspects play an important role. For example I’m a libra with my moon in Pisces and I have just met a guy who is a Libra with his moon in Capricorn. He seems loyal and no disrespect , but if I had slept with him by now then I don’t think he would be respecting me the way he is. I’m not being judgemental.
