Today I was thinking exactly the same.

My partner has been vey busy lately, and we are long distance. And I've tried to be understaning with him and being more independent. But many things are happening in my life and I don't feel he is close or connected, so I just lose interest in sharing things with him and I become cold. I am not sure if this is a protest behaviour, since I don't have anxiety anymore. I am just tired of asking for connection and I don't feel like that anymore, so I just stop being that nice and supportive. He has noticed and asked what happened, and I just told him the truth. I think is another way of fearing connection. I don't feel safe enough when he is not close to me, so I try to approach. And when it doesn't work or my body doesn't want to try anymore, I kind of disconnect.
