Question

Could you rephrase this sentence?

I just want  the best for you, and have your best interest at hear.

Thank you!

Answer

I would suggest that you either join the clauses with "because" or make it two separate sentences:

I just want the best for you because I have your best interest at heart.

I just want the best for you. I have your best interest at heart.

Answer

I just want the best for you because I have your best interest at heart.

I have your best interest at heart and that is why I want the best for you.
