My dh and I didn't argue much and were neither prone to sulking, sex was quite vanilla but always good, he was tall, good looking and intelligent, and very easy going, which I thought was a good example for me, as I tend to worry. Neither of us were the jealous type and we gave each other space. He mowed the lawn, took the rubbish out, sorted out the car and did the driving, worked hard all day. So if I ever had negative thoughts about the relationship over the 20 years we were together, I'd remind myself of all those positive points and how great they were, and feel bad for casting doubt on it. I like to be a positive person.
So when the children were young and my going back to work didn't work out, because he did so much overtime that I couldn't even get an evening job, and he never took time off when the kids were ill, so my employer got fed up with me taking time off ... I reminded myself that I was lucky because of all the other things he brought to the relationship, and felt bad for complaining.
And when I did get a job, and told him about an order I had got, and he smiled benevolently and hilariously joked that he would soon be able to retire ... I felt bad for thinking that he was patronising, as I really couldn't complain. There were so many positive points.
Just as a couple of examples.
So then after 20 years he found another woman and treated me like crap. And now I can look back without feeling I have to remind myself of all the positive points. Sure, there were many positive points. But there were also many negative points that I shouldn't have put up with just out of a feeling of gratitude for the good things, and guilt over complaining about someone who "brought so much into the relationship". Guilt which was pretty much encouraged by my dh.
I now have a boyfriend; we have no plans to move in together or anything but are both enjoying the bf/gf relationship. So he doesn't take the bins out or anything. He's not super good-looking. But even so, I can think of a dozen great things he brings into the relationship. I'm a positive person, I can always think of things. But now I am also watching out for the negative things, too, and checking whether those are things I am willing to put up with. And if not, I'm out.
