Good guys aren’t enough

This guy I’ve been talking to for a year now which is basically my BF but… Na…
How do I start to not feel like I’m a bad person for wanting me time? Or wanting to not be in a relationship? Or wanting to have a man who is stable. I’m 23 and I just don’t wanna be the woman who settles because the guy is nice.
How do I start to feel like… It’s ok for me to want to be alone and want better even if the guy is nice

have some aspirations. and fucking spine.
