I usually don’t double post in a thread but I disagree with so many comments.
First of all what friendship are you talking about there was never a friendship, the guy wanted to seduce the girl and he failed, he says it feels different now, off course a few days ago he thought he could sleep with the girl now he knows all he can do is buy her free drinks, if you want a great friendship just call your real friends and play some smash or something, don’t you have enough friends already?
For girls it’s very convenient to friend zone guys they get free company, free meals, free entertainment etc, no wonder all men dread the friend zone while girls say it’s wonderful to have “close friends”.
Another thing I disagree is the idea to become cold because people want what they can’t get, if she liked you she should be kissing your feet right now, if she doesn’t, being stone cold won’t change that.
Like someone said if you want to be more attractive to women find yourself a good job and earn good money, going to the gym could help too. Lower your expectation Might be a good idea, maybe you are searching for women who are out of your league.
This is a fairly rough view to take of girls, you know if you have a guy friend who enjoys your company... you're not buying them drinks at bars or paying for their meals if you meet for lunch right? Having a girl in your group of friends is the same as that... but she has a vagina. Feeling the urge to pay for their stuff or that they expect you to pay for theirs isn't a friendship there is something wrong with that relationship right there.
As for the OP, I think you should just suck it up and move on, I mean if you do have loads of feelings for her and you end up pairing her up with another guy you're just going to be always secretly hoping that he isn't good for her or that they argue and she see's the error of her ways and comes back to you... the real fact of the matter is that all relationships have ups and downs, those aren't going to result in her back in your arms or if they do she'll probably regret it fairly heavily as the thing that's ruining her other relationship and you'll just be the blame for that. There are quite literally plenty more fish in the sea, she isn't into you in that way, put her on the shelf as someone you chat on messenger with for a laugh or whatever but the relationship thing, put that in the same prio as all your other friends, if you wanna go hang out if you got free time go for it, don't be tripping over your boner when she clicks her fingers for your company, if you got something else on you gotta have her in your mind as the mate she is, not who you want her to be.
Also gotta say this... if she gets a boyfriend, he isn't going to be letting her spend any time around you, as much as you'll be the guy she tells him not to worry about, no guy lets his girl hang about someone that clearly is hungry for her.
(you could see if she has an interest in watching some 80s sitcoms with you.. such as the Cosby show!)
