Is it normal that i forgave them both
My boyfriend(lets call him X) and I met in high school and have still been together three years since then. We both also are really good friends with this one girl(Y) that I have known since our freshman year. So about three months ago, my boyfriend confessed to me that six months prior to that, he and Y were talking to each other on the phone about what it would be like if he was dating her instead, for about a week. This devastated me and caused me to cry for hours- I wanted to die. X apologized heavily and promised that they never did anything other than talk about it. That still didn't help. I've spoken to Y and she told that she no longer thinks of X like that, that he's like a brother to her now. So X and I are still together and we all try to hang out with Y and her current boyfriend. I still feel this prang of jealously whenever I think of Y. And then X bought Y a N64 for no apparent reason other than she said she wanted one. I thought the gift was too much and I'm angry at X for getting her that, and at Y for accepting it. I keep trying to play it cool, and act like the whole thing never happened, but when my feelings get the best of me I act out and X gets angry at me.
IS IT NORMAL that I forgave them both so easily like that? Or am I overreacting with my jealously and crying when all they really did was talk? I love X and I want to stay with him, and Y was always a good friend to me before. Can acting like it never happened between us really work and we can continue to hang out?
