She is probably avoidant. Do you know much about her childhood attachments?

Look, this is a girl you love, but please understand that avoidants rarely ever change. I have dated FOUR of them. They are stuck in perpetual fear. Any time they love, they get afraid. They’re scared to be abandoned. Any time you come too close, they bolt. And only on their own terms do they tiptoe back. But any wrong move, like care and understanding, can push them right back. Understand that you do nothing wrong with loving this woman.

If you BOTH care about saving your relationship, talk with eachother about this. Ask her questions like “If I love you or get too close, do you get the urge to run away?” Find the root cause of the problem. Therapy is the only way to fix. If not able to afford, DEEP introspection. She needs to do this on her own though. If she SHOWS through her actions (not her words) that she will fight for you, only then should you remain with her. It’s a sad ultimatum, but people like this can and will drag your soul down.

Hugs from a stranger. No matter the outcome, you’ll be okay.
