Meaning of 愛されてる証拠だ


How do I read this? I think it means proof that that I am loved but I am
unsure. Is she saying something like the fact that he is not going to go
anywhere (stay by her side) is proof that she is loved?

> 彼女「どうだ？ ちゃんと帰って来た気持ちは」  
>  彼「もう……どこにも行ったりしません……」  
>  彼女「くすっ、そうか、よかった、愛されてる証拠だ」
