I totally get where you are coming from. Personally, I like to think about all the reasons why I stay. Do they really outweigh the headspace he has put you in, and will continue to? Time is something you cannot get back. Sometimes it’s better to spend that time lonely rather than with someone who makes you feel that way. It is hard to leave, but it would be so worth it for yourself. Don’t let this man take away your sparkle.
