Wrong response. You have to validate why she feels that way. Instead you should have said. "I understand why you feel that way. I'm going to keep our private lives to ourselves." That's what you don't understand. It's not HER problem. YOU aren't giving her the support she needs. But you can learn to.
And BTW, she's right about your friend. According to you polyamory allows you to "love" different people at the same time. Swinging is different because there are no real 'feelings' involved. However, like I said before, the same problems apply. Women mostly will have a tendency to fall in love with OP because that's how many women are.
You aren't seeing to her needs for security. That's why you're in this mess right now.
