Stop playing with his feeling by saying things like you like him when you have no intentions.
その気も無い – no intentions
好きだの何だの – things like you like
言って – say
気持ちを弄ぶな – stop playing
彼の気持ち - his feelings
大切な友人が浮気されて深く落ち込んでいます
A good friend is being cheated on and is deeply depressed.
浮気したクセにあなたが好きだよと言って弄ぶ最低な奴にガツンと言ってやりたいんです
Even though she cheated on him, she keeps saying she loves him and is playing with his emotions so I want to give him a good talking to.
いい加減誠実な人間になれ！とも言ってやりたいです
I would also like to tell her to grow up and be a sincere person.
情けない - Miserable
