my wife left, but still lives with me #2/continued

[tough spot]

I guess if I am starting to feel slightly resentful/frustrated at our situation I would imagine she must feel even more so. I try to give her space, no emails, no texts, no conversation about R. But we still live in the same house and sleep in the same bed so as far as 'giving space' goes, it is somewhat limited.

She is taking the kids to a hockey game tomorrow and she invited me along. A month ago I would have jumped at the chance...now I am not so sure. I would probably enjoy the trip but I wonder at the same time if I am shooting myself in the foot long term. Should i take this opportunity to spend time with her, or give her even more 'space' and politely decline?
