I will say you were being a little too sensitive that's why he acted cold after your performancr. I am a scorpio and we tend to make up "problems" in our head. When he teases you he likes you but you made it serious and that is what pissed him up. You can say you wasn't making him jealous but you knew fully well you walking in there with a guy period would come off as playing games reguardless of your actions. The problem you seem to have is MISS COMMUNICATION. You guys are both a little childish and need to learn how to communicate and that is something you are going to have to teach him so you need to learn how to communicate without assuming he is being "mean" to you. Manipulation will not work even being in denial that you don't do it.
Nah he just was caught up in the moment he doesn't even know you yet he needs to put more time in. I dated a Gemini in the beginning of the year tried to tell me the same thing I never said it back because reality is he didn't know me. You have to watch out for things like that. I'm a romantic but I'm practical so take that with a grain of salt for now. Words are just words for air signs and Mercury people.
He put on his cap to "save" her. The guy is a total prick and thank goodness you didn't marry that marker. He clearly has issues and feel guilty that you called him out on his lies. He obviously made that story up about the guy to through you off! Words mean nothing it's his actions that showed you his true character. Don't worry he will cheat on the next girl too.
Some men would jump over the moon to get you back just to treat you the same way they ways have. Stay strong and find a life outside of him...he may change and he may not but if you decide to take him back and he dies the same things you need to give him the divorce papers and closed the door on him.
A person cannot love you beyond their character. A man can't give you 100% of him until he meets his basic needs which is security, protect, and provide. You were the man in this relationship and if he stated any longer you would've resented him. This is a lesson to stop ignoring red flags you need a man to take care of you not the other way around. He needs to find himself and you need to rebuild your self esteem so you can stop dating a man's potential.
