Hi you (((((((((complic8d)))))))))) I don't think I've seen you post in a while.
I do that a lot - not just in a therapeutic relationship either. Sad thing is, I'm painfully aware of it and you'd think as a psych major and after doing research I could fix it in myself... nope, not a chance!
There are a ton of articles on self-sabotage on Google (yes, even in relationships) so if you want to check them out - they're really interesting.
