I think it was 10 months before I said I love you. In fact he freaked me out because he said it after about 3-4 months. In past relationships it took about 15 months or so before I said it IF I said it at all.

I have had several relationships where it was a bone of contention because the guy would say I love you and I would answer with I really care about you. However, I will say that I have a GREAT deal of attaching to people, a plethora of trust issues and am damaged on fundamental levels by my upbringing so I am probably not the best gauge for this
