Good points throughout....and the list can go on and on and vary for each and every person.
"Having to be established in your job/career in order to be worthy of being in a relationship with someone"
This was one I didn't realize I did years ago when I went through a rough patch financially and felt like I would be a burden to a partner so didn't date during that period.
Just nonsensical, the other person decides whether they want to date someone that may or may not have their stuff together, you don't decide it for them.
