I still have feelings for her.我对她还有感情.

中文里说我们对某人有「感觉」指的就是对别人那份感情还在. 英文的用法也十分类似, 老美也说, have feelings for someone. 特别是当他们提到自己的前任男女朋友时, 常会说, "I still have feelings for her/him." 意思就是缘分未尽, 心里上还是喜欢人家的.

注意一下 feeling 指「感觉」时用的是单数, 例如 "I don't have a good feeling about this." (我觉得这件事不好), 但当「感情」讲时多半用的是复数, feelings, 例如 "No hard feelings." (不要难过), "I still have feelings for her." 都是.
