<human>: Can you provide a brief overview of the text?

I know I am in the wrong here, I'm not trying to explain my actions. Please don't be too harsh without advice. I just want to stop this awful habit and treat my boyfriend the right way. 

Lately, when my boyfriend does not do something I want, I pout or say something that I think might change his mind. 

For instance, last night we and some friends were about to go out together to eat and he called me about five minutes before we all met up to say he had a head ache and didn't want to go. I had been driving all day and said "it's okay if you don't go but I don't feel sympathy for you because you know I'm running on no sleep and have literally just driven home from a road trip (for scholastic reasons, think little sleep and lots of lectures)." Or I'll say something like "okay, I'll just do this fun thing (kayaking, watching the sunrise etc) that you're rejecting with someone else if I have to". 

The good news is my boyfriend does not fall for it in anyway. He stands firm in his decisions. He's mentioned one time I seemed like I was trying to bully him and he wouldn't let me. Other than that instance, (which was more of a direct push for what I want, than an emotional tactic) he's not mentioned it. I want to kick this before it ruins our relationship. 

I know that what I'm doing is manipulative and wrong. I hate that I've been doing this lately. I didn't realize I've developed this habit until last night. I'd like to accept when my  boyfriend says no and not try to change his mind using emotionally manipulative tactics. It's a really douche move. What can I do to consciously break this habit?

What do you say, reddit? Can you help me be less of a dick?
<bot>: I've been really Dickish when my boyfriend cancels plans or rejects an idea. How can I do better about accepting no as an answer gracefully?
