My general situation is that we have been together for almost nine years. I'm happy, she's happy and problems between us are few and far between.
That in itself is one major difference!

However, when I stop and think about it, there are so many aspects of our life together here that are different from my experience of (quite a few

1. Behaviour in company or in public.
Probably a bit more 'restrained' here.
Limited physical contact.
Wouldn't dream of talking about the more intimate aspects of our relationship, and certainly not our sex life.
2. We spend a lot of time in the together in the house, but often in different rooms. (I can't abide the sound of Thai TV, spend a lot of time on my computer and have a 32" TV as my monitor.)
We don't often eat together because we (usually) eat different things at different times.
3. Judging from so many posts and threads on here, this might be unusual, but I've never had a relationship with the level of mutual trust that has developed between us.
4. I am the 'breadwinner'.
5. Very few arguments and moods.
There are more, but time is short.
