In fact I believe it is the opposite. In times like these I would expect there to be misunderstandings and it can be difficult to discuss these topics. I have a friend who for as long as I have known him turns to humor in uncomfortable and emotionally charged situations. It's just a reaction he has and so standing at a wake or something he may suddenly say something inappropriate. He means no harm or foul by it, it's just some odd psychological thing that happens. When he has done it with me standing next to him, I will usually interject with something like "Well, that was an interesting choice of words." or something to open the door to allow him to acknowledge the ill-timed comedy. Most people that know him expect it from him now so, mostly it does not cause too much of a stir. 

In fact he not long ago wanted me to read over a letter he wrote to his children to be read in the event of his death. I did not really want to read it because I thought it would be too personal and felt like I should not be looking at something like that. He insisted and got a bit angry when I tried to avoid it. So, I read it. It began:

"Well, if you are reading this, I am dead. Sorry for your loss. Obviously, my loss here is pretty big too." and continued into ridiculousness from there. 

He wanted my opinion of what he wrote and I said "I assume your kids are well aware of your sense of humor, so I am sure this will feel like their final talk with you and you most certainly are here in this letter." 

He asked "Do you think they will understand that I love them? Does that come through?" 

I said "You come through in this so, yes, I think they will feel the love in it."

Both you and David write here with a great deal of emotion, I know because I do as well. It may come out in different ways but it is honest and true. I don't think David would write something to you that was so clearly personal and an attempt to explain why he felt the way he does, unless he believed you would be able to understand it and he wanted to communicate something to you. You don't do that with someone if all you want them to do is to fuck off. 

Not speaking for David here, just giving you my point of view on it. Nobody is telling you to leave. Misunderstandings happen, but if you find visits here and interactions with the people here worthwhile, hopefully you can see clear to talking it out and getting to the other side of it. I know you have expressed your love for us and I know you meant no harm with anything you said.
