I'm glad your therapy helped, sorta ?

I don't think any of it was about being "good enough" for him. You asked him and he told you he isn't looking for a relationship right now and his interest with you id friendship, and that is Okay. You may not like his answer but it is what it is.

You can't make anyone want you , like you , need you or love you. It either happens or it doesn't. Both parties need to feel the same.

Just move on with your life. If you are unable to stop obsessing over him and whether he is online or not, maybe its time to turn off the computer and go outside, take a walk, find other ways to connect with people.

Good luck with whatever you decide to do.
