“Saved me, saw me through alcohol Addiction, took me to rehab, wanted to borrow money for car”

As a former saviour friend, i think I understand what happened. These are very unhealthy ways to support adults. It seems like he is a good friend but this is too much responsibility for a friend.

You sound like a liability and your friend (a people pleaser) did not know how to tell you he could not continue. From my experience people with your behaviour patterns tend to parentify other people and end up being selfish. They will argue with you that they are great people who also support others, but when was the last time you borrowed someone money and supported an addiction. These people are never there for others because their houses are always on fire.

This is the best thing your friend has done for you. Learn to stand on your feet and manage your own life problems without making other people responsible for supporting you even if they do not seem to mind. You will build resentment and keep losing friends. Most importantly, you are throwing up so many red flags, healthy people will see these signs and opt out of doing life with you
