Given everyone inevitably has a hard time once in a while: What do you when a friend, lover, or the like inevitably has a hard time?

If not, that could be why. I had a very nice friend who tried to get me to use mushrooms. I told this friend that I didn't have an interest in that, but she can do whatever she wants. I don't judge her if she likes that, but I want no part of it myself. Then she tried a few more times to convince me and tell me how great they are. I replied the same way I had originally ("no thanks, please don't bring it up again"). Her repeated questions about it and subtle pressure let me know that she doesn't respect my autonomy, my lived experience, and my ability to make my own effing decisions. We're not teenagers either. This same attitude came up with some other boundary related stuff too. It was obvious that she doesn't get it even when I told her directly in attempt to help her understand. I don't have time to deal with people who try to push their preferences on me. If I speak frankly about my boundaries and it goes in one ear and out the other, then there's no sense being closely involved any more. Maybe you have something going on with listening skills or boundaries with people?

There's anything wrong with you. If anything, the one who leaves a relationship abruptly without explaining why is the one who needs to work on their behaviour. You sound like you genuinely care about being a considerate friend/partner, what more could someone ask for? Don't be so hard on yourself. Some of us just have terrible luck and attract all the wrong people or subconsciously choose the wrong people when we're feeling down and insecure. The love you'd give to them, turn it inwards, keep growing and sharing, the relationships will happen eventually. Take care.
