I’m so sorry this happened. Something similar happened to me during my breakup. My ex got clouded and convinced by everything his family told him (like I feared) and he was convinced he didn’t love me and breaking up with me would solve all his problems. I was fine after, all the stress was gone and he was a mess. Now he knows he didn’t mean it and is trying to redeem himself in all aspects of his life, including me. Trust your gut and do what feels right for YOU. Not what others think or say.
Maybe you both need a break, I knew that if it wasn’t him, I would ask for one. See how you both feel about everything and reconvene. It will feel refreshing. She might be stressed by other things she isn’t able to tell you. It doesn’t mean she should take it out on you, but it is hard to control those things sometimes. Just be there for you and her, whatever you decide, you will both be okay 🫶
