i never said i love to anyone before i met my current my boyfriend, becoz my previous relationship never lasted longer than 2 months, never had chance to say.
last year i went out with my bf, i think about a month, onenite, he was trying to say it, but took he 5 min to complete the sentence lol,what i can remember is, he said ermm, ermmmm, ermmm....... im ..... erm.... pretty sure.... i love you stuff.... ermm then 30 secs silence, i said ermmmmm. i love you to i think.
HTH?
your bf may just shy? i was pretty shy, never thought saying it in first place.
