Well, you can’t. Its like you cant make him wear only pink t shirt. All you can do is make the person values you more than others. And it will make him choose you among others.
I don’t know how old are you. And are you already in relationship with the person or not. we cant make him want only you because there will always be another person out there with better choice.
Theres a different stages of relationship: building friendship, dating, in serious relationship, or marriage. Every stage have different approach. For example: in marriage you should be intimate with your spouse in everything (physically and emotionally), in dating you cant be that intimate, why? Because more you intimate with someone more easily you get hurt when you broke up. And for guy they will soon loose interest with the girl, when the girl so easily bare literally everything for the guy.
If you want him to want you. Try to make yourself as a girl with values. If you want relationship to last you want someone who love you because he values you as a girl that he can love and respect. You don’t want to be with someone who fall in love with the “easy” girl anyway.
Again, in dating relationship, is the good chance to know each other better. He might be not “the one” for you and its ok. Woman usually so easy to get attached with man in deep level when the relationship itself still immature. Don’t t get too easy want him to become yours. See if his worth it or not. And make him pursue you, be the kind of woman that worth pursuing. if he’s the one for you and if he really like you, he will want you.
Don’t t go over miles to makes him want you. Like you are already the wife, when you still his girlfriend. Or play girlfriend, when you still his friend (or even worse, when he doesn’t even know that you are existed). Build relationship naturally, don’t run to another stage of relationship carelessly. Take it easy and enjoy the flow
