Where you go ,i will go with you同义句

若在爱情的语境,此乃“执子之手,与子偕老”或是“在天愿作比翼鸟,在地愿为连理枝”"问世间情为何物?直教人生死相许."之类的
同义的句子——My heart will go on. Nothing gonne change my love for you .Never leave you alone.Take my breath away.Only you.
正统点的可以这样说Wherever you are,I will be your side.(爱情,友情都通用)
若表达友情的话——肝胆相照,不离不弃,一生相伴.
海内存知己,天涯若比邻
丈夫志四海,万里犹比邻
相知无远近,万里尚为邻
Whatever you do I will right there on your side.
Wherever you go, you will never be alone because of me.(这两句是我一位忘年之交对我写的一封信的两句,原句是Whatever I do you will right there on my side.Wherever I go, I will never be alone because of you.)珍重,my friend.

还有一个就是——我是你的影.（这个可用于很多地方）——I am your shadow.
形影相随 ——peas and carrots
希望我的回答可以帮到你.
