I don't think you can truly say it's love and you need to be together if you're not together. It's just hope, excitement, hormones.
Not that those aren't reason enough or no one would ever have a second date, but some people are far too grandiose about their feelings.
I want to eye roll when I read "I've been secretly in love with another man for ten years, I see him once a year at Christmas, should I tell him/DH?" etc.
