Being hurt is going to happen regardless of exterior factors or confidence. Dating is like a job interview. Some people just aren’t a good fit. Sometimes it seems like constant rejection when young because most young people aren’t formed yet and have no idea who they are or what they want in life or in dating. They don’t understand attraction in an organic way, but let’s it only serve their ego due to neglect and abandonment issues as a child. We’ve all seen the beautiful waif who chases abusive boys or the handsome jock who only likes the cold nag. Fake it until you make it is good for building your own confidence through goal setting, but people who are fairly worldly can see it. Everyone’s mask slips eventually. It’s better imho to be as authentic to who you really are so you attract someone who appreciates you for yourself and some mirage you have to keep projecting to keep them around. Too many want to change their partners. Most times it’s because they accepted affection or attraction under false advertisements.
