I could be projecting from my sitch to yours but if you automatically assumed (mind read) that her being on the computer meant she was avoiding you/ didn't want to spend time with you/was rejecting you - you may well have been wrong.
This was one of our bugaboos - we'd each do insulating activities to shield ourselves from the rejection of the other not wanting to be with us.... when really all we both wanted was to be together and be wanted. Big ol' narsty feedback loop.
The trouble with having an open mind is that people put things in it.
