I think you've answered your own question when you said above 'Had i known it was leading to this i would not have got involved'. It's not what you want, so end it, and if you still want a relationship, look for someone you're more compatible with.
I used to say with my first husband, that in a perfect world we would buy two houses next door to each other, as that way I wouldn't have to put up with his leaving the loo seat up, lid off the toothpaste, picking up his dirty socks, etc., and he wouldn't have to worry about my leaving washing on the airer, which always annoyed him, and my other little habits, after all, we all have them, don't we? I felt it would help keep the relationship fresh, as when we were in bad moods we wouldn't have to see each other, and when we did want to see each other, I would feel more like making the effort to dress up, etc. Sadly, although the relationship did last 15 years, eventually all these little habits wore us down, and we began to irritate each other, so we went our own separate ways.
Your DP's way isn't necessarily wrong OP, but it's not for you, so end it, and move on.
