Do not consider myself a "people pleaser" by any means but I have let things slide when it comes to loved ones. Not a lot of stuff but "too much" in hindsight. I've gotten better over the years and now it's a situational issue.
For example, pretty sure my current relationship is one of codependency. Things are much more complicated than I'm willing to say atm. But yes, I have been in a codependent relationship and it sucks. And depending on what kind of dependency you fall under (or if you're the one someone is dependent on), you can feel trapped.
