Advice ? Am I selfish?

Question

So I’m going out with a guy and everything is good we’ve been together for almost a year I’d say and things are going well.  But something is bothering me and it’s going to sound really selfish if that’s even the word to use  ( I don’t think it is but I can’t think of the right one right now). 
So there have been numerous occasions where my man has seen me struggle. For example one day I saw him before work and we went to a shop together. I got some of my favourite snacks and went to the counter finding out that the card payment is minimum £5. So because I had no change I was like fuck it I’ll leave it. Now I know my man said he could pay for it and I declined but I feel like he should’ve done it anyway regardless if I said no. 
That’s just 1 of many examples I could give. And I know it sounds bad because my boyfriend doesn’t owe me anything and if I declined the offer it’s my fault because I said no. But am I wrong to feel upset or annoyed that he didn’t? Like I’d want him to have ‘no babe I got this and I’m not taking no for an answer ‘ energy.  what are your opinions???  Am I just being a bitch??? Am I making any sense??
Edit : 
Some of you girls are hella bitter in the comments telling me to grow up and stop being a brat or immature. I asked for advice not for you bitches to be up my ass. Might as well lick it damn

Answer

It’d be nice if people could read our minds, but that’s why communication is so important. Be assertive and ask for what you want!

Answer

That’s childish as hell and you’re wrong and petty for having a problem with it. Don’t act like a brat and expect him to read your childish mind. It’s not cute and you’ll find yourself single real soon if you don’t knock it off.

Answer

You said no, I don't know why u think he would insist on paying. Most men aren't gonna sit there and analyze and guess does she really mean yes. He's not thinking your no is actually a yes. Just say what u mean, and mean what u say so there is no confusion.

Answer

Not only are you being selfish but you're being immature and having a thinking error of assuming people should read your mind. Why would you want a man to not respect your "no"? If you say no regardless of what it's about then he should respect that. I think its ridiculous that you want him to disregard your answer.  If you want the help then accept it or ask for it.

Answer

It’s terribly unfair of you to be upset with him for doing what you asked.  Take responsibility for your own actions.

Answer

Yes that's petty as hell. Grow up and stop playing games. Learn to communicate like an adult.

Answer

He can’t read your mind, sis. Communicate with your partner. Tell him exactly what you want.

Answer

He’s not a mind reader if u said no how is he supposed to know you really meant yes use your words and say what you want and say what you mean

Answer

So you said No and you’re mad he listened to what you said? If you want him to always veto what you say and do otherwise then I don’t think it would make for a good relationship. Grow up and learn how to communicate

Answer

You have to say what you mean and mean what you say when it comes to men. My husband will not help me unless I specifically ask. He’s just that type.
