HOW MAKE YOUR GIRL HAPPY

1. Admit when you're wrong and don't be too stubborn . If you really messed up, you might want to plan a special date to apologize. When you're wrong, don't act like it was her fault. Don't just apologize, though - back it up with actions. And Always give her a cooling period if she's really mad, then offer to work it out. Remember, communication and compromise works, not talking it out doesn't.
2. Go out of your way to spend time with her but give her some space too. Try to clear enough time for a romantic dinner or, more casually, a movie. If it's just not possible, at least make the effort to talk to her, but don't overdo it.
3. Don't nag. Don't seem too needy; she'll find it annoying. Don't act like she should be grateful for your company, either.
4. Show that you're genuinely glad to see her. Be glad to see her and show that you are not faking or exaggerating it. If your usual first reaction isn't a smile, there may be something wrong with the relationship. If you're just having a bad day, put it aside and grin. A hug can't hurt once in a while either, but don't crowd her or struggle to build up a budding relationship with lots of affection.
5. Never cut her off or act uninterested in what she has to say. That's not to say don't interrupt at all - sometimes what you have to say can't wait. But if this happens, return to the subject she was on. If she seems a little hurt, apologize (not profusely. A simple 'sorry' will do). Don't just change the subject to something else.
6. Remember that no means no. Don't pressure her for sex if she's not ready! Always test the waters first, with both words and actions. As your relationship progresses, you can start to get more physical, but take it very slowly. If she seems hesitant, back off - even if she doesn't say anything. She'll open up in time. (If she's an abuse survivor or something along those lines, that's a different situation entirely. Get her to talk to someone if she's not already.)
7. Laugh at her jokes. If they're not funny and you're not good at faking, don't try - a fake laugh is much worse than none at all. But try to make an effort. At least smile; everyone likes to think that they're funny.
8. Do not show romantic interest in her friends. Not even a single one of them.
9. Always tell the truth. No matter how much it hurts. Cause in the end, the truth is all that matters and if you lie and she finds out, you'll get screwed a lot more than if you told the truth and it hurts. Why would you lie anyways? Just make the truth as nice as possible without twisting it.
