Dating is not about figuring out how to behave to get the other person to like you. Sooner or later your true feelings and values will come out anyways. Dating is about finding a person that you are compatible with and has the same values.

So you dislike her going completely silent for over a week. Not even a text now and then or a call every few days. Its totally viable and understandable that you dislike that. Now its not about changing your own character to accomodate her. It is about telling her that you dislike this behavior and then you can find a compromise or you walk away.

You say she knows you will always be there for her. If she knows you are simping she has no respect for you anyways. She thinks she is the price and you are lucky to have her maybe.

So my honest advice here is. Have some selfrespect and either tell her that this bevior is not okay and if she keeps behaving that way or, even better, just walk away. If it is like that after 4 months then this relationship is going down the drains eventually anyways. You can now go out of it, having learned a valuable life lessen and get a more suitable woman for the next or you let her trample your ego for a while longer until she dumps you for the next best guy when she gets bored of you.
