I see. Well, that doesn’t sound so much like “stealing” a kiss as “sort of stumbling into it”. If you both thought of the same thing, then that’s fine. These things do happen naturally.

When it comes to intimacy, I don’t think it depends on your “label” so much as it does on how you and your partner are ready for and into the same level of contact. It’s OK to ask, “Can I kiss you?” just like it’s ok to ask, “How do you feel about being exclusive right from the start?”

And yes, she didn’t treat you as well as she should have. And life happens every day.

All the best.
