“一厢情愿”与“一相情愿”怎么翻译成英文？？

我非常负责地告诉你，一相情愿和一厢情愿其实是一个意思。我查了汉语词典了。所以可以翻译成相同的：
wishful thinking on one's part.

例如： 我认为她的情况正在改善, 但这也许是我一厢情愿的想法.
I think her condition is improving but it may just be wishful thinking on my part.

（to do something）only out of one's wish

一相情愿 love at first sight

Wishful thinking

One-sideds wish

一厢情愿——one's own wishful thinking
