I am feeling like a little bitch right now. I was fooling around with a girl I'm dating and she said something like "there was only one guy I liked as much as I like you". She was obviously subconsciously (or not) shit-testing me and I knew I should not have reacted, but unfortunately I did.

Something similar happened with a previous girl. This shit is like my Achilles' heel and it bothers me very much, so much that I think I lost a bit of attraction for her and my heart physically hurts when I keep thinking back to this, but I don't want it to! How do I fight this?
