I have to remind myself that my choice was what *I* needed. Sometimes he acts a bit "put-upon" that he has to be a neutral party and it actually makes me feel guilty.
This is how you have been conditioned to feel... . many children in dysfunctional families are made to feel responsible for other people's feelings.
It's not your job to make sure your brother isn't uncomfortable. He has choices, too. If he is feeling resentment, it is his job to deal with that. You aren't responsible for his choices or how he feels as a result. He could choose to be *truly* neutral and not bring up your FOO in conversation, rather than making passive-aggressive digs at you. He could focus on his relationship with you, or be honest about how the present situation makes him feel. His happiness is his responsibility. It is his job to learn to cope with reality in a healthy way.
When you feel guilt as a result of talking with your brother, what are the specific thouhts you have? What true statements can you use to replace them?
For example:
"I am weak and oversensitive because I should be able to handle my FOO," might become instead, "I am a strong person for protecting myself from abuse and manipulation."
"I am such a cruel person for causing my brother so much trouble," could be, "I am lovable even when other people don't lile my choices," or "I am not responsible for managing other people's feelings."
What thoughts need replacing, and which statements will be helpful for you? Do you need any boundaries with your brother, or to openly discuss what you are both feeling instead of "mind-reading?"
