Oh Mimi,
I really feel that more men should be able to cope with tears and hitting, really, I do.
It does sound like you were perhaps a tad mental for a first date.
What would I do? (This is not something to rely upon of course). If I liked the person, which I believe you do, I would say thusly:
I absolutely don't blame you, I must have seemed like a right loon.
In my defence I can say only that I had had a most traumatic week and got terribly carried away. I honestly do not normally carry on like that. (some lying essential)
I do of course completely understand your feelings about it and will respect them. Should you ever fancy a normal and low key cup of tea one afternoon by way of compensation, you know where I am.
