I think we have a normal relationship. I hope this doesn't sound smug. I do know we are lucky.
We help each other and do things for each other. Not because we a 'doormats', just because we want to make the other one happy, or to take a bit of stress from their life. I will do something like clean his car, BECAUSE I know it will make him happy. He will bring me a bowl of raspberries and a cup of tea when I am ironing, because he knows it will make me laugh and I will enjoy it.
I married a feminist. That helps. DH respects that I work bloody hard, as does he. He mostly cooks, I mostly clean, but it is not set in stone. He has never seen something as my job because I am a woman, and had an equal, if different ,role in bringing up the children.
In one of my jobs we work together, and we still cant really see enough of each other. No in a 'do everything-joined at the hip', just that he is interesting, funny and calming and I want to be near him. Probably he feels the same about me :)
We are cuddly, affectionate and embarrass the children by kissing in public!
We do not play games, set tests, deceive each other, use physical force in any way, sulk, give each other silent treatment, we dont swear at each other, call each other names, talk each other down to other people, criticise each other, get 'pissed off' with each other,none of that.
We act as adults towards each other.
It helps that we are both very calm and relaxed people who do not 'sweat the small stuff'. It helps that we do not have any serious money problems. It helps that we have similar views about how to bring up the children. It helps hat we are both introverted and like our own space, and respect that in the other. It helps that we have the same sense of humor. In an odd way it helps that in some things we are totally opposite. I am not bothered about music, he could not care less about art. He loves to travel, I love to 'nest'. BUT that doesn't mean that we are not suited, just that we are individuals.
Not everything is perfect, and we do have some problems, some things are reresolved by talking, some things we have still not got resolved. Some things we have decided to ignore and pretend they don't exist, because to face them would be too painful.
We married within six months of meeting and have been married for nearly 25 years.
