Love is about give and take. Sometimes we have to give more and do more in order not to lose what we´ve got.

My try.

Sevgi, vermek ve almaktýr. Bazen sahip olduðumuzu kaybetmemek için daha vermemiz ve daha yapmamýz gerek.

Not sure about the ´about give and take´.

Also the ´what we´ve got´, don´t know whether in this case ´have got´ can be translated with ´sahip olmak´.

Corrections please!

not only "daha". it needs a "çok". "...daha çok vermemiz ve almamýz gerekir"

sahip olduðumuz is a nice translation. common usage is sahip olduklarýmýz in plural as there is not only one thing we have.
