Attachment can suck sometimes. I thought I'd never find someone better than ex-T. Even after I started seeing T, I didn't think I'd attach to her. I actually told her I hated her at one point. But, over time, I did attach to her, and our relationship was/is healthy. Then I found L. I have never felt so nurtured and loved. Both T and L have taught me what healthy love looks like, and that not everyone will abandon you. That's all to say, no, she's not the only one who loves you. All of us here love you. Your family loves you. And you will find more people to love you too! Her saying that no one will love you more speaks to her insecurities, not to the quality of person you are.

One other thing that might help (it's helped me). Respect is greater than care, and care is greater than love. Love feels great, but it can be unhealthy, even abusive. Respect is utmost important. And next is care: to care about you, your wants and needs, your boundaries, your well-being.

I think your T loved you in her own way. But from what you've said, she didn't seem to respect you or care for you. You were caring for her most of the time.

I'm sorry you had to experience this.
