what's the longest youve not just loved someone but been actually in love with someone ?

Dunno. It's a strange thing when you've separated, because you might still love the "idea" of them, but they're constantly changing; so, it isn't necessarily them you love as time goes on, while you're apart.

If I include only interests that I've actively been with, then prolly around 2 years. If I include after we broke up, I don't even know. 5+ probably. At the same time, who's to say whether that's love or just hormones, availability, and gauged value.
