Move on, learn from your mistakes, and don't assume that because someone did that once or twice, that is an embedded habit in their DNA. Merely a mistake in judgment, unless they demonstrate that same behavior for you.
This is, in my view, incredibly important. Assumptions constrain our thinking ... by not getting 'at' the truth and not letting our minds grow past our own stereotypes and perceptions. Not to mention the fact too many deal breakers and red flags constrain our dating pool.
Am I advocating not having deal breakers or red flags ... nope. There's some sort of middle ground to be had!
