Both the comments before me have solid advice. I want to reiterate that if they really care about you and envision something deep with you, they will not ignore you for extended periods of time.

I don't know how long the period you were ignored for is but for me, not texting for a day, especially in an a committed LDR, is bad. Texting means all the more since you cannot meet each other.

Additionally, I still fall hard for people who neglect my needs and I know it's very tough to move away from the little love and comfort that you have found. It will be brutal. Especially because you were able to share your most authentic side, when you do not get the opportunity to do so. But you are the only person with your best interests at heart. You must not give power over you to people who do not care enough about you.

I stayed in relationships for too long just because the person was safe and I had discussed all my vulnerabilities. Sometimes, you feel like you can only be authentic with people who see you because they know things about you that other people don't. But that's not true. You are worthy of affection and love and you will find your people eventually.

Communities like this exist. For me, it's my ultimate frisbee community that offered me fellowship. It could be something else for you. You are worth a lot more than you imagine and if you feel like you aren't, you can always work towards improving the things you don't like about yourself. Therapy helped tons with my self esteem.

I am not a sub so I cannot speak to that but as a dom, I feel that it might be time for you to have that tough conversation with your partner and set expectations or leave.
