How would my man feels if i send him a flower telling him how sorry i am for nagging him bec of my jealousy? ?

We're in a long-distance relationship and he is angry at me for the things i accused him. I want to say sorry and he likes to give me flowers before but now he is mad, I want to show him that I am sweet as that girl who has been flirting with him and cooking for him (she makes excuses to see him). Please help me I would like guys opinion. Women please tell me also if it's a good idea. Thanks.
