普通のシェアメイトや女友達になら私はここまで思いません。わたしは、彼女とあなたが、心の深い部分で親しくなりすぎていると感じ、また、彼女もそれを分かっているため、あなたと彼女が仲良くしているのを見るのが辛いのです。
私には、私がこれだけ嫌だと言っているのに妻よりも彼女との付き合いが大事だと言っているように思えるんです。また、あなたは彼女には忍耐強く説明したり話しかけるのに、私にはすぐにキレて、突き放すような会話しかしないのが悲しいです。
As for me, even though I've been saying I hate it, I am able to think now that being together with her is important than my wife.
Also, even though you very patiently explained it to her, she immediately got angry at me and talking only coldly to me made me sad.
To me you are telling me she’s more important than your wife is to you even though I have been telling you I hate it like this. Also, seems like you are being so patient talking to her explaining her something but to me you get offended very easily and talk to me like you just want to kick me out or something and this makes me feel so sad.
For me, you seems to say to me that even though I do not like it, but you prefer her more than me.
Also, you speak and explain to her with efforts, you are quickly getting angry with me and only can talk like pushing me away, and that I feel really sad.
Though I said to you that I hate that, it seems that you think it more important to have a relationship with her rather than your wife. And, it also makes me sad that, even though you talk and explain to her with patience, you soon get angry to me and you want to have no more talk with me.
