I think this statement has a few revealing layers in it
Yes, you have the option of no longer being ‘in this relationship.’
However, you are having this current difficulty with feeling abandoned/neglected while the relationship is continuing.
So you’re currently feeling abandoned/neglected, while also feeling unable to leave (because of the emotional bonds).
This puts you in a trap (as @Shashank describes).
The key is that the emotional bonds are also creating the feeling of abandoned-neglected.
You feel ‘attached’ to her, and therefore times when she is not around, or not expressing interest in you, or placing her attention elsewhere, must feel threatening, because they fail to reify those bonds.
This reminds me of a date I went on a few months back:
We had a great time together, the conversation was free-flowing and she seemed to like me. I was thinking that it would work out! But something funny happened partway through our date: a couple of her friends came along to say hi. I noticed that she had that same easy manner with them… she was just a relaxed person, she mostly liked people and has an easy time getting along with everyone. She turned out to not want to pursue more dates, and I learned something.
The date seemed like ‘something special’ to me, because it was one of the easier interactions I had ever had with a girl I was attracted to. But for her, it was just another interaction, because she was having nice interactions like that all the time.
Could it be that something similar is happening with you and your partner? You are both having a wonderful time when you’re together, but perhaps she is also enjoying those other parts of her life, to the point that she will prioritize those other things.
Can you say the same? What is your life like when she is not around? That may be the reason for feeling abandoned & neglected… it only makes sense to feel that way when one is in some kind of ‘trouble’ physically or emotionally.
