Translation - Portuguese brazilian-Latin - Por onde for, quero ser seu par.

Your translation: "Quoquo eas, par tuum volo esse".
And your bridge: "Wherever you'll go, I want to be your partner".

Hm...

Wherever --> ubicumque, quocomque... but quoquo?

par tuum - your equal

to be a partner - you should think it over once again I think... I can't do it for you, sorry...

Thanks for your patience, Aneta.

I hope it's OK now.

coniugem?? from what noun? It seems to be a verb "coniugo,-are" in coniunctivus praesentis...

Moreover, I'm not convinced that we can mix here the moods... I would use here two "coniunctivi" (for both clauses). It is like a coditional, though without "si", so: "modus potentialis"...

I would be very grateful if you changed also the order of the second part (a bit), please...

"Coniugem" isn't a verbal form, but the accusative of "coniux".

I hope the word order is OK now.

But "coniu(n)x" is rather for a husbant or a wife... It was used only in this cases by Roman people... So, I don't like it. Ok, I propose "socius" here...

But you didn't change a mood at all:
volo --> coniunctivus...

Typical LATIN order is with a predicate at the end of the sentence...

That's why I can barely translate into Latin, and only short sentences...

"socium tuum velim esse" -->

"socius tuus esse velim"

This is a kind of a predicate... In Polish: "orzeczenie imienne", I don't know English name for it...

Compare, please these two sentences:

socius tuus sum - I am your partner
socius tuus esse velim - I'd like to be your partner

Don't worry and don't give up, please. It wasn't easy sentence...
You usually translate into Latin very well...
