Well my wife texted me a joke yesterday which I didn't bother responding to. Apparently that bothered her because she texted me this morning "Did your phone die?". I sent back a simple no. And she said "You never responded to me yesterday. I thought something was wrong." I just told her I was busy.
Now she's testing me to see if I'll contact her. She had some medical tests done today and was going to text me after. She didn't I think to get me to contact her.
I feel so much better today. I've stopped emotionally investing myself in each interaction and it's very liberating.
