Hey, this is my first time posting a question here, so lets cut to the chase.

I have this girl that I really like and she likes me back, but she plays tricks to get me, (she doesn't know I like her) and there is one trick I will never forget. So I called her 3 times before yesterday and 2 times yesterday,(the bowling day was yesterday)then my mom drove me over to pick her up, but mom got the wrong street, so I called my crush's house and she wasn't there, so I asked her older sister where my crush was, and turns out she was AT THE BEACH! She didn't even tell us she was going to the beach and she DIDN'T EVEN SAY SORRY! My mom was angry and she knows that person is my crush, so she tried to make me happy because after that, I was miserable all day! My mom told me this was a trick to show she has a bad side, by ditching bowling without telling us, but that trick just made me hate her more and now I think I should go find someone else, I really like her, but I don't know what to do! Is she worth it?

I don't think she is playing tricks to get you, she is just rude and maybe she knows you like her and thinks it's funny to be rude.
Move on. Someone like that is not worth the energy.

But the thing is she is usually nice which is why I asked this question.

She may be nice but her actions were thoughtless and rude. Maybe that was her tacky way of telling you she does not like you and did not want to go.
Move on.

This was just nasty of her to do. In my opinion, that's not a trick to get someone... it's more of a nasty thing to do to someone to blow them off if you don't care about them. It sounds to me like you are putting more into this whole thing than she is. I would suggest that if this is the way things are right now, forget about her and find someone that isn't so self centered.

My mom says girls are like hell even though they seem like angels, ALL girls, but I think my crush wanted to show a bad side because she is always nice, but I know she likes me, I'm sure of it, there were lots of signs and I can't back down now, I will find a solution to it, thanks anyway :)

That's not just showing a bad side. She was outright rude and nasty. You guys had this planned and she even knew your mother was going to be inconvenienced to give you guys a ride. She changed her plans and didn't even have the courtesy to call and tell you or your mother. That's not a bad side. There are plenty of other ways to show a bad side without having done this.

I think if you continue with her, even if it somehow works out now, you're going to be sorry down the road.

Good luck.

All girls are not this way. The majority of girls are not this way.
If you continue to go after her she may continue to be rude and play games because you are just following her around like an obedient puppy and letting her treat you any kind of way.
She is not the only girl in the world. Don't act desperate, it is not attractive. Leave this girl alone.

Thank u so much for helping me guys, it means a lot, I will make my decision and hopefully it's the right one.

I've made my decision, I am going to be mean back, the first step is to delete her from my Facebook, the first step to payback, lol...

You can delete her from your face book if you want but she probably won't even care.
The best payback is to get over her and be happy. Don't stoop to her level.
