I don't think it's bad communication on either of their parts. It's fear. They truly love and need each other. As if it wasn't complicated enough to be in love with your best friend, your support system, they also have to deal with the fact that they are both men. Coming out is something that is hard, even for adults. And if their relationship as lovers fails, it could ruin a friendship that has taken a life time to built.
They are so toxic for each other because they don't know any other way, that is how life has taught them to be. But I'm rooting for them because they can help each other heal. They just need to learn to control their damned tempers!
