How do you make a guy become obsessed lol?

Quite simply: you can’t.

You can never make people feel anything they don’t want to, all you can do it be yourself and make sure that you have a strong relationship. Keep it fun and fresh by trying different things on dates and making sure you have lots of laughs together. Show him you appreciate him and be loving and caring, but make sure you retain independence. One of the things that many people fail to do when immersed in a relationship is have a separate social life. Make sure you go out with friends aand are not avaible sometimes- that way you will make sure you have plenty to talk about when you do see your boyfriend. That will also show you are not dependent on him.

Be someone he can depend on and make sure you are always there for him if he needs and someone he can talk to about anything. A deep emotional bond will form attachments and make him feel very close to you, so you will know you are both well suited to each other and likely to last :)
