That's a good idea, but my problem is just this phrase in particular. I've already studied German, and I understand all the words involved...however not the implication I want to know if he's saying he loves me, or whether he just likes me. This phrase seems to be in the middle of the two (love and like) and for that reason I was wondering how native German speakers would interpret it.
Well, yes... you've already got the answer, even though I know it's hard to get. I normally use that when talking to my parents or my best friend. I do use it to talk to my boyfriend sometimes because it gets boring always saying the same thing. So, there you go. You need to get a feel for how your date interprets it at that specific time. Watch him while he is saying it.
But at the very least, it means that you two are close.
