Why is that people you date try to bring you down with issues from way back ?

yes I did stay with you for the mean time for free but I also asked you if you would like me to pay a portion to help out and they told me no, but later on bring up the issue as to them paying for everything and helping me out when I asked.

Even though they said I shouldn't have to ask you could of just handed them the money anyway out of heart.

I'm so confused because even If i didn't help put with the rent and I paid for other expenses as to food and trips. I would never understand how someone could be so selfish.
