OK - I believe you!
From your description of events it feels to me that you now deeply regret telling your male friend what happened as a consequence of both his response (disbelieving, you saw it the wrong way, perhaps you got it wrong etc), in conjunction with breaking off all communication (aka the silent treatment etc). When you were looking for some support and empathy by describing what happened ...
Is this not one of the classic scenarios of, "why o why did I say that to them when I knew how they were going to react". At the same time the content that was conveyed (along with possibly the manner in which it was described if you were having a down/traumatic day) was/is too much for the friendship to bear. Such that it breaks under the strain with both parties feeling even more hurt, pain and disappointment as a result, which hurts even more as you are already at a low point.
Perhaps the real question is how does one repair a friendship when one or both sides is not wanting to discuss or engage following either disclosure, argument or disagreement ? This is hard as both parties are most likely suffering but neither may feel able to reach out to each other! Further the content might be so extreme that neither feel like involving others, thereby leading to continued stalemate/pain as a consequence.
For what it's worth what you have learned is to be very careful who you share this information with. The trouble is that does not provide any solace. So perhaps the next step is to try and work out what is that will make you feel better within yourself ? (even a tiny, tiny bit better is something ...) Such an obvious question, if only the answer and getting there were so straight forward
I don't suspect any of the above will be of too much help, but at least someone took a few minutes to write a reply to you.
