The longer you put off saying what you want to say, both of your feelings are going to get further and further apart.
The longer you avoid conveying what you want to convey, the further apart you two will become.
ご質問ありがとうございます。
① "The longer you put off saying what you want to say,"＝「言いたいことを先延ばせばするほど、」
"both of your feelings are going to get further and further apart."＝「二人の気持ちは離れて行くばかりだよ。」
② "The longer you avoid conveying what you want to convey,"＝「伝えたいことを避ければ避けるほど」
"the further apart you two will become."＝「二人ともお互いから離れていくよ。」
ご参考になると幸いです。
