My codependent friend and roomie shares her relationship problems with me. If I engage or share anything personal, it inevitably turns into unqualified mutual therapy. This used to feel like care and bonding to me, but now it disgusts me. I become enmeshed and dysregulated for days or weeks. Months ago, I told her I couldn't discuss her problems anymore and I enjoyed a respite. But with her recent breakup, this pattern has resurfaced. I can't afford to engage like this anymore. What is healthy intimacy?
