I’ll give a perspective of what you’re describing playing out in my life currently. My gf basically betrayed my trust and she acknowledges that a reason behind her actions is that she let all of the small things she disliked about me control her view of the relationship. Now we’re in this place where we’re technically not together and she’s feeling all of these guilty feelings and the idea of me not being in her life anymore literally brings her to tears yet she can’t make a choice on what she wants. Although, the circumstances are different I say what I say because her behavior has honestly changed my view on our relationship as I feel like I’ve had to pull all of the weight in keeping us in each other’s lives. All it has done is made me more comfortable at the idea of moving on to a better situation with someone who’ll appreciate me for my flaws and everything that comes with being me. Basically, become clear on what you want out of the relationship and accept that maybe this one doesn’t suit your needs anymore and that it’s time to move on. It’s not fun being made to feel like you’re no adequate and being with someone who isn’t sure about you can be a mentally torturous things.
