The Crappy Childhood Fairy on YouTube talks about this. It's what divine1966 said. Healthy relationships feel boring to someone who's accustomed to drama. She says a good relationship should feel slow and boring in the beginning, but they aren't actually boring, they're normal and just feel boring to someone who's used to things feeling dramatic and exciting and chaotic.

Totally agree with the sentiment of taking a break from relationships and doing some work on yourself. Get to know and love yourself for a while. Once you love and respect that person, you'll be a little pickier about what you let yourself be put through.
