Hi Kate,
Please don’t take this the wrong way but I have to agree with Buddha that what you did is considered emotional cheating. To go from being just friends to a proposal prior to you breaking up with your ex bf is definitely cheating. He wouldn’t have proposed to you if he didn’t sense that you were romantically interested in him. Now even if you waited to breakup with your ex bf before accepting the proposal it’s still cheating. Also, I find it very unusual for a guy to make a proposal without any sort of intimacy.
Whatever it is, I hope you’re happy with your decision and wish you guys the best
😀
