My adventure with languages

I'm pretty sure you mean "languages", right?

Today, I want to talk about my adventure.

I'mve been with my wife since 2021 , and we got married in 2024.

When talking about a period of time that extends back into the past, we should use "I've been" instead of "I'm".

She's my paradise and representmeans everything forto me.

"...means everything to..." is more common and natural than "...represents everything for..."

Before her, I was a little gamer boy, and now I'm learning Italian, and Spanish, and I want to improve my English.

More sinceEven more so because of my son.

"since" is an odd word to use here. "Since" is similar to "because", but before just a noun and nothing else (in this case, "my son"), I would use "because of".
Example: "I'm staying inside because of the heat."

Also, I would say "even more so" instead of just "more". Though, I know all of this makes it a much longer sentence. A much shorter alternative to this entire sentence could be "But also for my son", but that doesn't have as much emphasis.

It's for his future that I'm sure to take thoese efforts.

Very minor change, but "these" feels more natural to me than "those".

It's incredible how can a life can change, and I'm sure now, M that my family is the most important thing.

It's all because of my family, who lives i on every continent.

More since my son.

I'm not sure what you're saying here, but it could be something like "I've been learning more since my son was born."

Your sentence wasn't necessarily wrong, just that it sounds a little bit weird (it sounds a little more like a old English poem, rather than a modern saying).

Before her, I was a little gamer boy and, but now I'm learning Italian, Spanish and want to improve my English.

The "Before" indicates that you want to make a contradiction (that were previously a "little gamer boy," but now you are not). This means that you should use "but" instead of "and."

More so since my son was born.

It's for his future that I'm sure, so I'm willing to take those efforts.

I could be misinterpreting what you were trying to say, so going off of exactly what your wrote it could instead be corrected to.
"It's for his future, so I must take those efforts" (The subtle difference in nuance is that in the first correction, the efforts are "optional", but in this correction, the efforts are "not optional")
