Price was talking to Soap when Soap asked him if he even knew what a soulmate was. Obviously he did and explained it to prove such.

Soap: So, you know what it is. How come you haven’t tried to ask your soulmate out before it’s too late?

Soap then pointed at you who was speaking to another soldier, the soldier’s hand on your shoulder and his humour awful. It didn’t sit right with Price, but when he looked at Soap to answer, he wasn’t gonna admit it.
