Have you ever kissed someone...and then halfway through the kiss thought... this is a mistake...?

Yes, I know how you feel. But realise it can't change anything. It doesn't affect you. So just learn everything is going to heal in time. (= (I kissed a female friend once... no ual attraction, it was just a dare. I suppose maybe that's the difference?) but yeah, she felt quite awkward, then I kissed her ont eh cheek and told her I loved her. Luckily, we're good friends and she saw the funny side so we're great again. <3
