Well, if I knew the age of the guy my response would be different. If you are over 25, my guess is the fact that you are friends at all means that he probably already has thought about it and may already want it too.
If you are young and just part of a circle of friends, then you interact with plenty of “guy friends” and he has plenty of friends who are girls, and you may not be on the same page. Just happen to bump into each other a lot.
Basically, your life situations dictate my response.
How you get a guy to see you as more than a friend? I try to explain this to girls on here from time to time – but it is super fucking embarrassing to make a move on a girl you are friends with to find out she is not into you. Happened to me once and it still makes me cringe. So just because he hasn’t made a move doesn’t mean anything. Don’t count on i happening though. If you want him, you need to drop hints and flirt. Talk about sex or flirt in general and you will know. But don’t force it. God, I am so glad I don’t have to deal with that shit anymore.
But if you are worried that he is worried about ‘ruining the friendship’, he is full of shit if he says that tired line. If he wants you, that ‘ruin the friendship’ nonsense is out the window. Friends or not, half the girls I was in a relationship with in my life we were ‘friends’ first, so being friends doesn’t mean anything, in my opinion. Personally, those were the best relationships. You could talk about stuff, laugh, fart, and fuck, and laugh about fucking, then fart again, and laugh about that. Heaven, right?
