"I think plenty of people do raise their concerns and find they fall on deaf ears. What can be a perfect and supportive relationship for one party (who is receiving all the support) can be an exhausting and draining relationship for the other (who is doing all the supporting) and, eventually tired of asking for something for him/herself, ends up looking for it
elsewhere."
That's very true Anna. I have known a few relationships that have broken down and the person who has wanted to "stay" has said things like "No we weren't happy but we still could have stayed married" - as though the need to be married is more important that the actual relationship.
Having such a NEEDY spouse is a bloody nightmare. Frankly you become not much more than a carer. I think that's why it's REALLY important to have a life outside of your family/marriage - to be an individual person in your own right with your own support networks, friends and interests.
I lived with a very needy spouse and it was like a constant weight on my shoulders. Yes there are things you can work through but there are also situations where frankly, you just grow into completely different people and are not suited any more. I am all for working through problems and suffering 'bad years' - I'm sure I have spent more time in relationship counselling than most people on this thread - but if you feel trapped in a marriage with the "wrong person" then it is a very dark and lonely place to be.
IME most affairs start from simple loneliness and misery and the need for a companion. Getting out of a crap marriage/relationship is a really hard thing to do by yourself, with no support from anyone (and frankly, if you are the person doing the 'leaving', then no one DOES want to offer you support).
I had several affairs when I was married - and several of my ex-lovers are now really close friends. Some of them helped me through really dark times in my life and provided me with a lot of support.
Of course it was still a shit thing to do to my ex-husband, and hurt and damaged my ex-husband a great deal. I want to say "And yes it was morally wrong" but when I think of the loving sex I had with some of my lovers, I find that hard to say. I find the "one cock for one vagina!" model of marriage, where you have set periods of 'separation' between each sexual relationship frankly a bit confusing. Sex has generally been an extension of the love I've felt for people in very confused and emotional circumstances. I am very envious of those of you who can separate the two things so cleanly. Frankly I have always found the whole arena blurry and messy.
