The only way to have healthy, rewarding, betrayal-free friendships is to demand blood-oath loyalty at all costs. None of this "empathy" nonsense. Friendship poison, that stuff is!
Lol, you joke, but some of us just seem to have a worse time of it with friends. Most likely, it's all the abusive family interaction I was subjected to growing up which has adversely affected my ability to choose the right friends. More often than not, I find myself in largely one-sided relationships. I have such a sunny, optimistic disposition by nature, I always want to think the best of people. Even the "troubled" type--probably, especially so, considering I'm pretty troubled myself. Inevitably, I get hurt over and over again, but somehow seem to lack the instinct for developing healthy defense mechanisms in response. Anymore, I've had to resort to extreme pessimism and suspicion of new people I meet, simply as a means of self-preservation. Keeping people at arm's length is just about the only way I've found yet to keep from getting continually hurt.
In fact, met up just yesterday with a longtime Facebook friend of mind whom I'd only briefly met in person a handful of times. (We were doing a "socially-distanced" trail hike, remaining min. 10ft. apart the whole time.) Purely automatically, I began to open myself up to her in a very generous manner, sharing certain vulnerabilities, far in excess of anything I've ever allowed myself to do with her online. I just don't seem to be able to help it. The moment I left for home, I pledged myself to basically ghost her for at least the next little while.
