<human>: I am a sophomore in college and I have been working with a start up for a year. I never expected payment; this was primarily for learning. I learned the owner was paying other for the same amount of work I was doing. I feel like I should be paid.

The owner is looking into investors and making a solid team. He wants me on his team. This would involve me owning equity and remaining in the business for 2 to 5 years.

I do graphic design. He said he'd paid for things; never did. I, stupidity, let it slide. This happened about 3 times. I recently told him that I didn't want to be on the team and I would like payment for the work I've previously provided for him.

The total is around 8k but he only wants to pay for the work he used. which would be about 4k. (He is arguing he paid for 2 things out of that 4k. So realistically if I do get paid it would be about 1.5k)

 He's given me about 750$ - 500$ would cover a flyer and failed launch. 250$ was for an unrelated social media thing.  

The reason a lot of stuff didn't get used is because of his miss guidance (wrong formatting/coloring/scrapping things all together.)

He has paid another graphic design and is giving her equity (because she cried!) I feel like I've been used and disrespected.

Even though I have told him I no longer want to work with him; He still comes to me for feedback and consultant work.

Should I demand payment and cut ties with him all together? I'm really at a loss of what to do.

Can you give me the gist of the text in a nutshell?
<bot>: I did a years worth of work for person (no payment) and feel used. Don't know if I should argue about getting paid, get equity, stay civil, or cut ties.***
