Do you agree that communication is important in a relationship ?

I met a woman on an LesbianSingles app just over a week ago, we exchanged numbers on WhatsApp to get to know each other better. At first we were texting each other quite a bit and a few days ago she asked me if I would be her girlfriend, we both agreed to stop talking to other people and delete the dating apps, with that being said now she rarely texts me anymore and I can’t even ask her how she’s going or what she’s been up to without her cutting me off. I feel like we don’t communicate enough and we literally go for hours without talking to each other but when I confronted her about it she claims she’s been busy but I feel like she doesn’t really want me in her life but she claims that she loves me yet she only has time for me when it suits her. It’s already difficult enough that we are in a long distance relationship because we live in two different states, we can’t see each other due to living in different parts of the same country plus with covid 19 restrictions being enforced, I feel like she is breadcrumbing me although she may or may not be doing it deliberately. Without constant communication I don’t really know if this relationship is going to work, I think I would be better off trying to find someone closer to me that lives in the same state, being in a long distance relationship isn’t easy. I really like this woman though so l don’t know what I should do.
