When he is feeling down, be there for him. Love him so he can know he has a girl who is always there by his side.
Don't be underneath him so much, because he will think that it will be hard to get a break from you.
Be quick to laugh, but don't be fake. When you laugh, mean it.
Be yourself. Don't change after you start going out. He asked you out for you, not for anyone else.
If you are happy to be with him, let him know. Smile often and let him know that your smile is all because of him.
Still flirt; don't give up just because you think you have him for good.
If you become friends with his friends, don't flirt or let them flirt with you. When a guy sees this, it makes him insecure, and he worries if one of his friends is giving you dirt on him. If one of his friends has the hots for you, completely ignore him. Your boyfriend is not mad at you, but he will have a problem with that friend.
Very important!--Don't worry about things. If you worry too much, he will be under the impression you don't trust him, and you run the risk of him thinking that you're paranoid unless he knows you have a reason not to trust him.
Cuddle with him. Bury yourself in him. Make his warmth your warmth.
Take care of yourself. Don't do things that could compromise the way you look or feel, and always be presentable, but don't overdo it on makeup.
Make sure you have really good hygiene. Guys are attracted to girls who smell good.
Take an interest in his friends. They may become your friends.
Try having deep conversations with him. If he is a deep thinker, he will react properly and find you more interesting instead of thinking you are someone who always talks about the same shallow subjects. Don't always be serious though - remember to have fun, too.
Communicate with him; be open to him about anything.
Trust him in every way, but only if he has earned your trust. Always be honest with him (and yourself). Never lie to him or keep secrets from him, but if he breaks this trust, don't keep telling him everything; you will only get hurt.
Support him through good and bad days. Just be there for him in any way you can, but remember to give him space to breathe, too.
Respect him the way you wish to be respected. Don't hurt, abuse, or neglect him in any way. Treat him the way that you would want him to treat you.
Make time for him and plan activities you will both enjoy. even play COD if you want to
Have your own personal time, separate from him when you pursue your own passions. Don't sacrifice this time or your time with friends for your boyfriend. It will show him that you are interesting and respect yourself, as well as giving him time to hang out with his other friends and be a guy.
Make something for him to remember you by. This will help to stop him getting distracted by other girls. you can go for a bracelet or a keychain if he has a car, just give him somethig to rimind him of you
tell him that you love him, and that he is the only one you want. However, do not say this unless you truly mean it. Make sure you stay true to this, and never cheat
When saying "good bye", make sure you kiss him, hug him, and whisper in his ear that you love him. Do not, however, behave in a clingy fashion, and once again, only do so if you mean it.
Occasionally make the first move. Men will not tell you, but they do not always like having to make the first move. A woman in control will make any man weak in the knees. So give it a go; it works. It's sexy.
Always look him in the eyes (but don't just blankly stare at him) when you talk. If you keep looking away, he'll think you don't feel comfortable around him. Your body language says a lot, and guys notice everything.
Compliment him (genuinely). Don't just tell him he's 'hot'; occasionally call him gorgeous, or handsome. It makes a welcome change. Or, if you don't feel comfortable using these words, compliment his hair, or If you have a problem with an aspect of your relationship with him, tell him, but make sure not to come across selfish or demanding or angry; make sure he knows that you still love him, and want to work on it to make things better. He will appreciate your effort into making your relationship work. However, this doesn't mean that you hive to nag at him about every little thing; this will just irritate him, and turn him ohis clothes, or how he smells. However, never compliment him falsely.
