Well, I'm very sorry you've had to suffer through an experience like this. I may begin by sort of quoting, or parapharasing one of your last lines... "If someone else would've told me this story, I'd have immediately told them that it's not their fault--& that they should never feel guilty or ashamed over it!" When intoxicated (as heavily as you were) it makes it extremely challenging, to, at times make sound judgements & wise decisions - with our best interests in mind. So, no sense in beating yourself up over that. I'm just thankful that he didn't take even further advantage of you, in your given state. Now, can you not clear the air with those that were in these Group Texts, or Messangers (sorry, I'm so naive to these things...)? Or even if it is others outside of that small circle, provided that you know who they are, perhaps there is a way to get your side of the story out there, and to present the truth? After that, it's up to them to take your word for it, but honestly, based on your descriptions of him in the beginning, where you attributed all of those rather distasteful labels &/or names to him, I don't know why you would ever want or wish to have any form of communication with him again.
This is one of the drawbacks of any form of communication by this mode, or means. That being, "print!" Because it is no easy to misinterpret the, "tone." As you said, you sent him some nice or complimentary things, that were on the generous or kind nature or variety. And although you'd all known of it's or their intent (the meaning of the message), for someone who is not in the know, and just looking at the words themselves (without this inside knowledge), you can see how he - or anybody, really - could get the wrong message. It's like with the phrase, "I love you." Now, I could say that ten different ways and give out ten different meanings. But without the proper context, it's not hard for things to get confusing. I hope it doesn't sound like I'm putting any sort of blame, or responsibility or accountability or shame on you. For you are the innocent victim here. All I'm trying to do, in the event that you didn't already understand, and so as to perhaps be able to prevent something like this from happening again in the future, is to point out where some things could have been done differently. And obviously, once you add or inject that much alcohol into the mix, sound logic & reasoning have a tendency to go out the window. I wish you well, and keep talking here if it helps! Take care.
