I'm in a LTR for one year. It started great, but as the time went on I slowly slipped and lost some frame and control. She was turning me in to her bitch.

I finally had enough, and tried to bring the relationship back to how it was. When she asked me to take her out somewhere I told her we're going if she's paying for herself, refused to go hang out with her friends- I dislike the crowd, stopped texting so much, stopped giving her verbal validation, started making various plans and activities without noticing/involving her. With every change I made I had to face verbal/nonverbal dissatisfaction from her, so it made me wonder- is it even possible to turn a relationship around, or is it better to start with someone new?
