"I do think I’m in love with you when I’m with you."

"But it’s awfully hard for me to stay in love with someone when I only see them every three months and when the only contact I have with them is through letters."

An interesting, early — 1947 — use of "them" for "him," from Jacqueline Lee Bouvier, writing, when she was 16, to a beau who was not JFK.
