Hello my precious,
you most probably not worth it.
As everybody says,
but u stole my heart for now.

Please translate in separate sentences thank you
Traduction
bonjour ma chère,
tu ne le mérites sûrement pas.
d'après chacun,
mais c'est toi qui détiens mon coeur à présent.
TN: I'm not sure of what you meant by separate sentences. Depending on the gender you'll have to keep "ma chère" (female) or switch to "mon cher" (male).
