That all sounds quite harmless Thethings but in reality infidelity rips families apart in the most agonising gut wrenching way. The innocent victims of it learn to carry on, but life is never the same again once you really understand that the closest person to you not only betrayed you, but enjoyed doing so.
I'm sure my exH cheated because he loved the novelty and the ego rush of having a new woman (or women in his case).
Does his pleasure excuse his lying to me for the whole of my adult life and the impact on our children who he professed to love? One of my DC says that she will always remember that it is better in life to be the cheater than the cheated. The others are adamant that they will never have a relationship and in one case at least I'm pretty sure that is true.
I don't really care whether he did it because he was weak or because he had not properly "exited our relationship" (he could have gone at any time just by saying that he wanted to go, I wouldn't have stopped him because I do understand that love can wither away over time. I will just never understand how you can feel so entitled that you feel able to cheat). I do believe you judge someone by their actions because that is how they tell you who they really are.
