Traducerea - Hindi-Engleză - मेरे दिल का है

My wife sent this to me as a romantic expression. I'm sure it is very sweet and wonderful and I want to be able to reply, but I can't find a complete or accurate translation. Please help. Thank you!

Before edit:
"Mere dil ka hai ye kehna ham ko hai saath mein rehna. Mujhe tumse mohabbat hai"

The second line can also mean "We are/have to live together."
