Just curious really.
I've been with my boyfriend for 18 months, recently moved in together.
His longest ever relationship prior to me was just over a year, so to him our relationship is 'long-term'
My SHORTEST relationship was 3.5 years, and the longest 10 years, so to me we're early days still.
(I'm late 30s, he's late 40s if that's relevant at all)
