I met DH at 21, straight from Uni. Am now late 30s and we have an ok relationship. We have 2 infant school age DCs, and have been married 10 yrs.
We are quite different people iyswim, and get on brilliantly half the time, but do argue (always have tbh) and like our own space/hobbies.
I have always been perceived by friends as the 'sorted' one. Good relationship, DCs, own house etc, and have quite a few close friends who had been long term single.
Then fairly recently 3 of my close friends have met lovely partners, settled down quite quick, moved in together, got engaged. And the DPs all seem so suited to them, loads in common. Like the person they were MEANT to meet iykwim.
I know its probably the thrill of the new relationship. DH and I are 17 yrs down the line, lots of responsibilities, and no time together, but part of me wonders whether people make better relationship choices in their late 30s than in their younger years.
