problem is you cannot put that kind of label on love. Your in love when your in love. Your under 18, you have no idea what true love is. In reality, most people will not know, truly, what "true love" is for years after they actually find it. Until then your going on what your perception of love is. In young people, that is much more often lust, not love. So many will say "I love you" way too soon and before they truly are. Not everyone, but most. If you are truly in love, you can never "not" love that person. If you can ever imagine something happening where you could say "I no longer love you", then you never truly loved that person. Certainly the WAY you love that person can change dramatically. for instance, you might be in love, then that person cheats on you, now you want nothing to do with that person. If you really loved them then you still love them but what they did makes it too painful to be with them. in my opinion anyway...
When we started dating, it took me 2 weeks to tell my now ex-wife I loved her. I dont regret saying it that soon. People are always afraid to say I love you to someone but will claim their love for coffee or tv show in an instant. You can call it other names if you want or pretend its not there, but in my book, its allright to love someone at first sight.
I don't think there is an average time to say I love you. Some people can say it within months, some years. But personally I think about year is enough time to know each other well, to know you can trust each other and to say and mean, I love you.
About a year I dated a girl slept with her and got into an argument with her and I tried to calm her down "relax I don't want you to be mad, I love you." She looked at me like I said "fuck you." Ever since then I told her "I really are about you" and she said "I are about you too." Guess some woman don't like to hear it til they know it's concrete fully commited one year relationship.
I've never had a boyfriend, and I've never really talked to someone long enough to develop feelings that deeply for them. However more recently I may have said those words to someone... after 8ish months of talking with them.
But I was also drunk and stupid so. Sober me wouldn't have said it.
Really depends on the relationship, plus if you feel like you fell in love on the 4th date you don't really want to spook your SO 3-6 months sounds about right. Besides actions speak louder than words...
He looked deep into my eyes and told me "That ass is fat" and I knew... I freaking knew he loved me. Took him about a day didn't see him afterwards but I know my love is out there and he loves me as much as I love him. <3
