I have NC for this. I know Mumsnet hates cheaters and I'm the one that did in this situation. As with everything there are two sides and reasons etc which I won't bore you all with. I'm genuinely interested to know how people perceive this though and I'm sure I'll get some answers I won't like but every time we have a serious relationship issue or chat it always boils down to me being the "cheater" even if the issue discussing isn't to do with that. We're in a rough place and he's just said that I broke the trust so basically he's the better person over all. It's such a final response to the issue that I don't feel I have any comeback as my betrayal trump's any crap behaviour on his part. Is this fair? Should I always then end up to blame because of what I did years ago?
