Every time you wanted to do something without your friend — hang out with others, say no to a plan, have time to yourself — they'd make you feel guilty. A sad face, a "fine, I guess I'll just be alone then," a comment that landed like a tiny hook. Nothing you could quite call mean. But somehow you kept ending up doing what they wanted, just to avoid the guilt. You're starting to notice that you feel responsible for their feelings all the time, like their happiness is your job — and that saying no to anything costs you more than it should.
