How much is too much?

How much is too much information when getting to know a person in the dating stage? Like if you tell someone you were a serial cheater in your previous relationships… is it wrong for the other person to assume you’ll do it again in the next? Like if we know 2+2 is 4 and 4+4 is 8, then wtf is this??? This day in time you really have to take things into consideration before moving forward with anyone. Can HONESTY be too hot to handle? That’s the real question.
