Looks like a song. It sounds like you want this translated? Anyway, 1. まさか。(No way.) 2. 私が誰よりも安心できて、(More than anyone who can make me safe.) 3. 信頼できて、(Who can be trustworthy.) 4. 大好きな相手よ。 (A partner to like/love.) 5. 恋する相手としては、(A partner who is in love) 6. この上ないわ 是什麼意思 -- The last 5 characters are Chinese in meaning. If it is only この上ないわ , then it means there is no one better referring back to #5.
