Answer:
When someone is being honest with you, sharing her feelings about your behaviors towards her or about her, it is a good idea to listen and think about what you are hearing.
Perhaps you feel that you are only being protective, but sometimes our behaviors can come across differently than we intend.
If someone said that to me, I would say something like “Really!? OK. I’m sorry; I don't mean to be possessive. Can you give me an example of when you thought I was acting possessive? If I understand better, I can change what I'm doing that makes you feel that way.”
So, if a friend or loved one tells you that something you do is hurtful to them, accept that their feelings are valid and ask how you can make them feel better.
