It sorta sounds like he might like you. I think it means that he will prove to you that he is mature and grown up... idk...
Like a friend or best friend your go to guy
It means a male friend.
Godly friend
It could mean one of two things. If you know the character of your friend's male friend then he may be concerned the two of you are fighting and want to help, or, yes he could like her. It's best to ask him and get to the bottom of it.
This probably means that he likes you, or you like him and you don't know it. Maybe it will happen soon..
With your friend (male) or your friend (female)
The are many variables that come into play in order to determine this. It depends on whether he's a platonic friend or a lover. A male friend will rarely tell another male friend that "he's your man". As males we have a unique way of interacting with our male friends. We would say something like "You're my boy". If this is in reference to a female/male friendship then it means he is there to support you and he cares for you at least as a friend. If you are a female dating a guy then it means he's yours exclusively and you can trust him. He wants you to know that your not alone and he's dedicated to the relationship.
he likes you
It means simply that he is a good friend to you. He possibly could care for you more than a friend, but that's something you will both have to figure out. Many people feel it's impossible to have a male friend (or female friend) but that is not true. When single I had several male friends, two in particular that were extremely close to me and there was not a sexual relationship involved. More like brother and sister. My husband had some female friends before we were married and I kept my close male friends as well and we often have them over for dinner with their spouses or, sometimes they come alone. There is no secret motive by doing so.
to get the courage to say something to the person you like or to go and say hi to a friend.
they like you as a friend
Amicissimus for a male friend. Amicissima for a female friend. Alternatively: Amicus carissimus for a male friend. Amica carissima for a female friend. These mean dearest friend.
