Don't feel so bad. I too have been guilty of neglect. Every MR probably goes through that as couples get comfortable and complacent. But sure most spouse would run off into the arms of other people. So don't put all the blame on yourself. Far too often in these cases the S being cheated on has no clue how the other WS feels. Some actual communication with myself and not other people certainly would helped in my own MR. But I won't dwell on that. Acknowledging your faults is the first step to improving yourself.
