我只相信你会一直陪着我。用英文怎么写？急！

I firmly believe that you'll always be there for me. 一定没错～（歌里还这么唱呢）

i believe you will be with me forever
you will accompany me forever
you and me will stay forever

The only thing I can be sure is that you will be my side forever.

I just believe that you will always be with me.

I just believe you will always at my side.

I just believe that you will be here with me forever.
