Well all major relationships start out with meeting a guy or a girl and liking him/her for her personality and usually looks. If you are shy, I'll let you know right now... you really limit your chances of getting a boyfriend/girlfriend because relationships are about talking and exchanging emotions.
So to get your crush? It's quite simple actually and depending on the person the process can be fast or slow. Follow these simple steps in order to impress your crush...
Steps To Get Your Crush For Guys And Girls:
1. Do not be shy, you should know a lot about this person and they should know a lot about you.
2. After you know this person, start complementing them, not obsessively but here and there throw in a "You look good today" or "I like your eyes". Complements really cant hurt.
3. After you guys are very good friends you can ask your friend if they want to hang out after school or whatever you are doing.
4. When you hang out the first time don't move to quickly just get to know the person more and make sure its the right person for you.
5. If the first date goes well then a second date is probably where the fireworks start to go off. If your crush wants a second date thats a green light for hand holding, frequent hugging, even kissing.
(No you don't have to be going out to kiss or make out)
6. Repeat step 5 until one of the two people make a move and ask the other to be their girlfriend/boyfriend.
7. Bingo, boyfriend/girlfriend accomplished.
Now don't rush this and don't go to slow, if you rush the other person will realize you are trying to hard and might be a bit uneasy. If you go to slow you are probably going to loose your chance.
I hope this helped.
