如果＂患得患失＂是　＂得到了又担心失掉＂的意思那： he always makes me feel like I might lose him. I'm always worried I'm going to loose him.

道歉，　楼上的都错了　别一直靠　金山　只类的词典做翻译．　我用了金山很长时间，　发现的错误不少． 因此呢，　我也不清楚怎么翻译但是绝对不能学楼上两为的英语． 有谁能用中文结实一下＂患得患失＂的意思吗？　词典不对！　be swayed by considerations of gain and loss　肯定是错的．

He's always = He has always (现在完成时)

He's always made me swayed by considerations of gains and losses. (强调从过去到现在一直保持这种状态)

He always let me be swayed by considerations of gain and loss.
