If a guy says he has feelings for you, what is he telling you?

This reminds me of a time I told a girl that I had a "thing" for her and her friend ended up obliterating me verbally the next day, good times. Anyway what he is saying, in general, is that he fancies you and probably would want to see where a more one on one relationship goes; however, he could mean that he cares about you as a person and as a friend. It depends on the person and the manner that you interact with them.

Depends what context he used it in, is he a friend who just said it to you out the blue, a guy you are just dating recently but not yet in a relationship, a husband, a long term boyfriend, a guy who lives in a cardboard box in an alley who screamed it at you in a drunken stupor.
A few extra details may make this vague question answerable.

Seriously? You're just being silly now. When a guy says they have feelings for you it means they love/like like you.

Most times I have found it means he's still sorting out those feelings, it might be lust, love, or in between. Keep your contact to a minimun, don't ask him about his comment, let him come to you.

It will work itself out. Good luck

He likes you in a more than friends way.
