Maybe you´ll think that all my posts are just about misfortunes that happen to me but it's what sells, and I wouldn't like to boringe you.

We are dance couples and I like her (a bit) for the way she dances with me.

First part doesn't really make sense. What do you mean?

Moreover, she´s beautiful, funny and skinnythin.

skinny sometimes has a negative feeling.

But all went to trassouth after a party, there, some things happened and made it weird.

not wrong but "went to trash" is not an idiomatic phrase. 'went south' is a similar idiomatic

Then we had a break for holly week.

holly week? is that a holiday? do you mean the tree?

I just saw her yesterday, where and we danced, but not like always, and I didn´t feel that match I had felt before.

Although we danced, it´s not too much, but is at is progress- I guess.

The teacher wants to change the dance couples, if he does, I don´t know what will happen.

it is now clear what you mean from earlier. but then it was not clear what 'dance couple' meant to me

I wishant things to go well between shme and meher, I really like her and wanna hang out together.

Alternatively: "You might be thinking that all my posts..."

So the story begins with me and a girl, whose name is Fanny.

We are dance couples and I like her (a bit) for the way she dances with me.

Present tense verbs in third person should usually end with an "s". "I dance, you dance, she dances, we dance, they dance."

Moreover, she´s beautiful, funny, and skinnylender.

"Skinny" works, but it feels a little more like a health condition. Something like "slender" or "slim" might work better.

But it all went to trash after a party, t. There, some things happened andthat made it weird.

First part isn't wrong, but a more common idiom would be "it all went downhill".
"It all went downhill after a party."

"There", used in this way, would usually start a new sentence.

"and" works at the end here, but "that" is just a little better in this sentence where we are talking about cause and effect.

Then we had a break for holHoly wWeek.

Please ignore this if you do actually mean "Holly". When I looked it up, I could only find "Holy Week", which just happened very recently.

I just saw her yesterday, where and we danced, but not like always, andbefore. I didn´t feel that match I had felt before.

A piece of advice I was given by an English teacher long ago was to always try to only have one "and" per sentence (not including "and's" that are in lists). It isn't something you HAVE to follow every time, especially not in very informal English, but it's a good general rule of thumb for making text feel cleaner.

We didn't mention a place before, so "I just saw her yesterday, where we danced" implies that you saw her IN the place where you two danced. However, something like "I just saw her yesterday in the classroom, where we danced" would imply that you then danced with her right there. (Without that comma separating "classroom" and "where", however, it will be "...in the classroom where we danced", and the meaning will be similar to the first sentence again).

Although we danced, it´s not too wasn't much, b. But is at is progress-, I guess.

The teacher wants to change the dance couples, i. If he does, I don´t know what will happen.

I wishhope things go well between sher and me, because I really like her and wanna hang out togetwith her.

"I wish", in this context, means you wish something had gone differently in the past. But "I hope" means you hope something goes a certain way in the future. "Wish" can also mean hoping for something in the future, but in that case it's pretty formal, and might be formatted differently: "I wish for things to go well...". This feels like something a royal figure or a very poetic person might say.

I've corrected the ending to sound a little more natural. But otherwise, it's not wrong at all!

Maybe I´ll write for you in the next post what happened that night - spoiler, it was like "Project X".
