Not really. The term soulmates doesn't necessarily refer to souls as they're described in religious or new age terms. It's simply a description for a special kind of affinity and compatibility with someone. No need to burden the concept with superstitious and mystical nonsense.
Do I believe there's some kind of mystical, foretold-by-destiny kind of link between 2 specific people? No.
Do I believe some humans are more compatible (on specific fronts) than others? Yes.
The soulmate concept typically has two important parts to it. The first is that these two people are bonded for life. The second is that these two people are more special to each other than any other person could be to either of them.
If you think about it, neither makes any sense if you are an atheist. Is it really possible to meet all of the billions of people on earth to find your soulmate?
