I've known this guy for 6 years but only been dating him for 2 months. Since about a month ago I keep thinking about it and want to say it when we're together but I don't. Sometimes one of us will slip up and say it when we are excited or drunk, then the other just gives a funny look (like, "oh yeah?). I think we both want to say it but aren't sure if it's too early. I think I am going to say it tomorrow because he is going out of state for a week.
nah, different for every person
Right after I'm sure it isn't lust.
Nah....you dont have to say it until you know it!
Right after they pay you!
not really. It would be odd to do so within a couple of weeks and probably not a good sign for the relationship if you still haven't after many months/years.
