Help me write a paragraph telling my boyfriend that “ I’m sorry he saw that my ex have sent me money and I hope this will never happen “

I want to apologize for any discomfort or insecurity you may have felt after seeing that my ex sent me money. It was completely unexpected and I assure you there is nothing going on between us. I hope this situation never happens again and I want you to know that you are the only one I care about and want to be with. Let's move forward and continue to build on our trust and love for each other.
