Need Help Understanding Taurus Man!!

Just go by his actions. The words will come when he's ready. He's taking it sloooww. If/when he does give you a verbal commitment, at least then you'll know he means it.
But at the end of the day, tolerate what you can tolerate. And he'll tolerate what he can tolerate.

Sidenote: Why don't people get this about Taurus'?! We take our sweet ass time! LOL

Your first mistake was devaluing yourself (in his eyes) by sleeping with him on the first night you met him (a virtual stranger)
Your second mistake was devaluing yourself further by continuing to see him on his terms only
Your third mistake was devaluing yourself even further by going back to him after finishing with him and going back on the same terms, thus showing him he can walk all over you
Your fourth mistake was telling him you loved him first (IMO men need to say this first, boosts their fragile egos)
Your fifth and worst mistake is that you are not listening when he tells you he doesn't see a relationship with you, if he says it now it will never change in the future.

This is nothing to do with slow going Taurus men.
