Is Love Is Living 3 Years?

Technically yours is correct and very stylistic. The correction is a question whereas your original is a statement you are posing as a question.

It is so sad whento see our relationship is changed.

Your original sentence is correct but it’s very awkward because “is” is present tense and “changed” is past tense, so I made the entire sentence present tense.
This allowed me to add “see” which makes the sentence less passive.

Today I saidtalked to my closely friend about things inaspects of our communication whenthat I really don’t like.

I think you are trying to say that you had a conversation with your friend about rough parts in your communication.
When you use “when” it sounds like you’re saying you had a conversation but you did not want to talk.

I feel free andam glad I talked to him but I am scared to lose a friend but. I think it was necessary.

Your original is correct, but you are saying “free” in a very metaphorical sense so I think “glad I talked” sounds better. Since “scared to lose a friend” is a sad thing and the first part is a happy thing we use “but” instead of and.
Using two conjunctions (and, but, etc.) in one sentence is not always easy so I would recommend making the second part a new sentence.
