Need Help Identifying a Song

It's a pop song that sounds like its from the 80s or maybe early 90s. Some of the lyrics that I can remember are:


Two as one
I want you, I need you
Two as one



I'm pretty sure this is a well known song but I just can't picture who sings it or what it is called. Thanks to anybody who can help me.
