No. I mean we've had occasional disagreements but not really ever an argument. Certainly no raised voices or unpleasantness.
But...
We have no shared children and similar attitudes towards our adult children so no conflict there.
Similar political views so no conflict there.
Similar attitudes towards money and housework so no conflict there.
Both work full.time and are flexible in approaches to the rest of life so no conflict there.
We're both considerate people, so no one feels/is taken advantage of, so no conflict there.
We're both quite laid back (eg no one cares if we're too tired to wash up before bed and if someone forgets to put the bins out, it's no big deal) so no conflict there.
Allowances are made for minor mistakes or errors in judgement and neither is of us is thoughtless or unkind so no conflict there.
We have both argued in previous relationships because there were conflicts.in some/all of these areas to some degree
We just don't really have anything to argue about because we usually agree. And, even when we don't, we disagree quietly and respectfully and are laughing again 2 mins later.
And, if that's dull, I'll take it because I grew up in a house with conflict and I know which is more pleasant and more fun!
