I'll take responsibility and spend 
the rest of my life with you.
.سأتحمل المسؤولية وأقضي بقية حياتي معك
Das werde ich, indem ich den Rest

La aceptaré y viviré
el resto de mi vida contigo.
La aceptaré y viviré
el resto de mi vida contigo.
Je le pense.
Mi assumerei le mie responsabilità 
e passerei la mia vita con te.
Assumirei a responsabilidade
e passarei o resto da minha vida com você.
Не стану отпираться
