How do I form a relationship with a girl?

That's actually a funny phenomenon. Often men can't get the women they want because of how they treat them. For instance, often guys will put girls on pedestals if they like them, This is pleaser behavior, and is the opposite of masculine. Guys will watch their words, be worried about saying the wrong thing, and this nervousness won't only show in your conversation, but also your body language. The more comfortable you are, the more likely you are to use more confident body language without even realizing it. Women also often grow in feelings the most when you aren't speaking to them, Odds are the girls you want, you try to text more often no? It's why constantly texting a girl you want, before she likes you... rarely works well. It's because that's what all guys do to try to Win her affection and that's the problem. You don't need to WIN her affection. Again, that's not masculine behavior.(we're not talking socially masculine but instinctive.) You trying to WIN her, makes it seem more like she's worth more. Which in turn means you are less. that's just subconscious. And the more attractive the woman, the less of these 'mistakes' it takes for her to swipe you off the list of possibilities, because of the more potential mates she can choose. If you don't want to be with a girl, just talk to her normally and try to not bring up sex or romantic topics. Either way you can't REALLY force a women not to like you. Unless your a prick, which has been STILL known to work at times. So best thing to do is let them off easy, and ask if they would still like to be friends if it happens. With relationships. Build a bit of rapport. Ask them what they're interested in, what they LOVE doing, and listen. This is especially easier on a dating site. Since I have a feeling it's difficult for you to walk up to women and talk to them on the fly in public.(Which you should practice anyways, the more comfortable you are around girls in general, the more likely you are to treat them with confidence.) Then IF you think she's interested(and there are ways to find out. Easier in person to tell however.), Ask her out. Don't waste time. She says yes, go for it, Set a specific Date and Time. And NEVER say yes to 'maybes' if a woman says maybe to your date, it means you are just a backup, or an option. So you can say "Oh nevermind then, Just call me next week when you're not busy and we might be able to set up a time." You are both people with equal value, your time is valuable. Remember that. Then when in the date, just ask her questions, say a few things during it so she knows you're paying attention. Tease her (Love is playful and fun.) a bit here and there, and if she shows physical signs of attraction, go for the kiss at the end of the date(or sooner if you are more confident in your skills.). Repeat process. Now obviously this is just the barebones of it all, But I'd be typing for hours if I wanted to get into the specifics. Could write a damn BOOK about it. But in short, Don't act Needy, Don't act like a pleaser, Have your own life going on(Hence your time is important.). Make her know you are interested not by sending her flowers immediately(Gifts are for girlfriends, not dates.) That's needy. You don't NEED to give her stuff to get her affection, because just like you, she is just a person. Talk about her, get to know her likes, hobbies, dreams ect. Girls, like stereotypes, usually love to talk, so as long as your listening, and jumping in here and there, they'll become more comfortable, and your work is already almost done. Now what's most important is. Not all girls will be interested, infact I'd argue 9/10 won't be. But you can't force attraction. So if you ask a girl out and she says no. Just suck it up, say okay thanks for you time and move on to the next girl you like. Again that's just a summary however. Dating is more of an art rather than a science.

I'm going to make it very short --- Friendship ---> Dating ---> Relationships You need to get to know this person first beforehand...

@Dʀᴀɢᴏɴ7 泽维尔 I mean you dont have to be friends first. Sometimes it just happens. Its preferred though. I laughed at the kirito/hinata thing. You have to treat them like good friends. All of them, the ones you like and the ones you dont like. However make it clear to the ones you arent interested in dating that you ARENT interested. Dont give them the "Oh Im not ready to date crap" Cause then they'll just wait around for you and be annoying. As for the girl you like. Treat her a little more special than the rest but not too noticeable or excessive. Keep her guessing, when you are sure shes into you then you talk to her about it. Dont go putting her on a pedestal like the previous user like 3 pages back said. Pedestals ruin everything.
