Being Selfish

I really struggle with being a martyr. I feel like if I’m not sacrificing myself for someone I’m not doing it right. I always prefer to be inconvenienced than inconvenience someone else but boy am I resentful towards them for it. I force them in this weird debt situation they didn’t know they were entering. This way when I mess up I can throw all the things I do for them in their face and they are forced to let go of my wrong. It’s crappy and immature. How do I put this in a model?
