"She called me up to come over and fix her garbage disposal which was not working. Since I was still in the area I went over and fixed it."
OK I don't care if you happened to be next door at a BBQ, stop doing things for her.
Really, continue going dark. Don't you see how back and forth she is?
If you are going to send papers to your spouse, you don't ask them to rub your back...you don't invite them for dinner...heck, you don't get angry and threaten them when they politely decline.
I really don't expect to see the papers. At this point, don't answer or return her calls.
And the next time she asks you to come over and hold her, or bring her something or fix something, etc. Just say no.
Say you are either in or out. You know I wanted and am willing to work on the marriage, but you clearly don't. I'm not going to give you back-rubs and come over to help you out, or allow you to fix my computer. We are either committed to working on the marriage, or we are not. I'm not playing this game anymore.
