I'm a Taurus female, and I don't know what exactly went wrong with you two but here's my take on it...
OPTION ONE: It was just a fight, and though he is hurt, he has forgiven and is trying to move past it.
OPTION TWO: It was more than "just a fight", and you sincerely hurt him, made him feel like you aimed to hurt him, or you did something that goes beyond your average lover's quarrel.
All I can say is.... once you GENUINELY and REALLY piss off a Taurus (and to us that is something else than having a "normal" fight or disagreement - we can deal with that), it's pretty much over. For Taurus, when it is over, it is over. I've had my share of disagreements and fights - and when I felt taken for granted, disrespected or underestimated... it was done. Over. Have a nice life. And if I ever was in touch with those people again, it was only because I HAD to or just to prove that I am better.
So yeah, once you really really hurt a Taurus, and they can't forgive you but suddenly contact you... you can bet that 95% of the time it is not out of deep love or sudden forgiveness. That doesn't even mean it has to be malicious (though with me it usually is if I contact you without forgiving you)... it can also be a fair but 'numb' attempt. When you really hurt a Taurus the feelings disappear for them, so even if he really wants to try again, his heart will never be in it like it used to be.
