Steps

You MUST create a sense of potential loss and reward when they seek validation. This will allow her to fully appreciate the value of the relationship.
2. You MUST give each other space. Seeing each other as much as possible will create too much comfort! When you reach a point of "discomfort" in life, that is when you realize you're making progress.
3. The first rule to keeping your girlfriend happy is to always call back when she asks you to.
4. Always get a small gift on every holiday. Not like Presidents Day but like Easter and Halloween. (Just a Hershey bar is fine)
5. Tell her secrets.
6. Don't tell her about other unrelated girls.
7. Don't lie to her EVER. This could cause her not to trust you.
8. If a friend is teasing her take her side or no side.
9. Always show up for a party 20 min early.
10. Tell her how much you care about her often.
11. Don't flirt, she will find out.
12. Make her laugh, try at least every time you see her.
13. One way to her heart is through her friends too, so try to make them happy.
14. Take her out to eat and not let her pay for anything.
15. Tell her she is beautiful, don't overdo it. Do it when she least expects it. If you say it too many times than it will be meaningless.
16. Just be yourself.
17. If at any time she asks you "Do these make me look fat?" just look her dead in the eyes and say no. This is the only case in which you can violate rule 7.
18. Never ignore her . NEVER


Tips

* Be sure to spend time alone with your girlfriend.
* Listen to what she says and say little along with it.
* Gifts don't need reasons to be given. Give her gifts on normal days. If you have no idea what gift to be given, send her a letter (begin with the least affection).
* Do little things, she will be thankful for them; things like opening doors for her or pick up her pencil when it falls.
* Get to know her favorite music band and find a song that you like so you can have a topic to talk to her about.
* Try getting her a gift for a surprise once in awhile.
* Whenever you smile, really mean it. Look into her eyes and smile as if you were seeing them twinkle. It makes you feel really happy and comfortable with each other.
* Remember: girls love romance. There is nothing a girl likes more than a nice candlelit dinner. Be an outstanding boyfriend and actually think about your girlfriend and her needs. In return, she should do the same


Warnings

* As said earlier, NEVER EVER LIE TO HER! She'll know when you do.
* Spend as little time as possible with other girls, you can still be friends with most of them!BUT NEVER PUT THEM BEFORE HER...if you want to keep her
* Best friends and family can NOT come before your girlfriend and never ditch her for them.But know how to balance everyone in your life.
* When you hug her make sure you do it how she wants you to.
* DO NOT EVER say you are going to kill yourself, even if you are kidding, she will not take it well.
* Make sure you know her well before you follow ALL of these steps, not all girls will want you to do everything on this list. But most girls will like you to do small things like opening doors and stuff like that and that will make you more admirable.
* Some will take the small things as insults. Like they feel like you opening the door for them means that you think they can't do it themselves.
* Don't talk about sex all the time, or they may think your with them for the sex and not for the love. Obviously sex comes with it, but only an extremely small percentage.
* A relationship is more than casualy dating another, it takes time, and that is what she will appreciate the most
