See above comment

We studied together medecine and go to the collogemedicine together and go to college together, we live together in an arpartment.

This sentence says that you studied (past tense) together but still (present) go to college together, this could be changed to add further clarity.
For example: We studied medicine together at the same college - this means that you have finished studying and you went to the same college while you were studying but you don't go there anymore

Tom and I know us than whave known eachother since we were children been .

The meaning of this sentence is a little unclear. The correction I have made means that you met Tom when you were a child and have known eachother since then.

He is so nice and good(adjective) .

I would use a different adjective instead of good. Good is not an adjective we use often to describe people unless we are saying they are a good (kind, ethical, moral) person, if this is what you are trying to say than leaving good in is fine, otherwise I would try using a different adjective like smart or funny.

When I was sick she to takeok care of of me .

This sentence needs was to show that you were sick in the past. I have changed she to he because he is the male pronoun we use, I presume he would use this pronoun since he is your boyfriend which indicates that he is male.

He cooks for me and, cleans, and watch with mes movies with me.

When you list things in English you put commas between the different things in the list and then put and between the last two things on the list.

He is very smart and after the stepenium we are married .

If you are Married to Tom than you should say he is your husband not your boyfriend. I am unsure what stepenium is meant to mean in this sentence so I removed it for clarity.

My parents and his parents are good friends and they try gooto be kind.

(try good) is unclear in meaning. Try to be kind is most likely the closest thing to what you were trying to say

Tom and I do iIn our free time Tom and I do many things, we hicke in the nature and go surfing ato the beach serving .

But myour dates are onare the best. Tom makeplans wonderful dates with flowers and restaurants .

The meaning of this sentence is unclear. If you are trying to say that going on dates is better than going to the beach or hiking, than the correction I have made is what you would say.

Once he surprised me with yellow flowers and chocolate h. He is very a nice guy and I love him so much.
