Having a degree(s) and a decent job/money does not make you a good person or someone who’s ready for a healthy relationship. Folks be arrogant, insecure, no personality, etc. because they believe those things make them “high value” and just ignore the need for therapy/inner work.
You get tested the most when it’s time for you to elevate. When you feel like falling back into your old patterns, remember why you started, remember where you’re headed, think of how great it will be to get there, and keep going. Your future self will be proud.
