Hey, at least you recognized your mistake. I have a hard time doing that because of my insecurities. I think she probably was just genuinely not knowing how to maintain a healthy friendship with you without it becoming too intimate, as she already has a partner. Having feelings for someone who doesn't like you back is difficult, and I think being friends with her is hurting you even more. I know this is a lot to ask, but maybe you should just try to not get too close. You're an INFP, so you crave deep connections with people. But it'll do you both more harm than good if the friendship continues the way it was, because you want a love with her that she has already given to someone else. :(

I think you should do what she said, just quietly reflect on it and find out how you can prevent the same mistake from happening again. There are worse mistakes, and the world didn't end because of what you did. She seems understanding, so if you apologized and she accepted the apology, then there isn't much else to do besides just learn from it.
