Falling in and out of love is one thing, falling into bed with a person you are not married to, whilst being married, is another. It requires a choice and it requires action.
I totally agree. This is a really stupid, short sighted, cruel, disrespectful way of dealing with the low points in the relationship. I think we delude ourselves that relationships and marriage are all "Disney, happily ever after" and this just doesnt exist. I feel a realistic approach, that your love will be up and down, is essential. My H and I talked about this a lot together and were very pragmatic, the grass isn't always greener etc. He even understood the neurological process of the initial falling in Love feeling and how this is fleeting and why so many people chase and chase that feeling moving from one person to the next!
Because a choice is being made I guess the only way you can forgive is if the spouse takes responsibility for that choice and take responsibility for the hurt it causes. This is remorse.
I know that when you feel depressed you make choices that not the best ones to make and you have a distorted view of the world. However, I have to say that I have suffered with depression and I have never ever intentionally hurt anyone else but I know I have said and done things that were hurtful to my H without doing it knowingly. This is why you need a trusted "other opinion" as to whether you are thinking and acting straight!
I just feel, given what my H has expressed in the past 15 years, he is completely different person with a whole new set of values. Now this seems like a crisis to me and it's not him. I therefore feel like I can understand his actions as wrong, just plain wrong. So that makes me see that it is not my fault and not that I didn't love enough or I didn't love him unconditionally. It remains to be seen if his crisis follows the pattern of MLC, but if it does I will be relieved because it does explain his cruel, callous and selfish behaviour.
