Dream of person

I was laying with my husband in our room in our bed together when we hear a knock at the door, my husband gets up and says its just my best friend coming over. He leaves the room and a moment later his friend comes in and gets under the covers with me. I say what are you doing as i'm getting out of bed and covering myself. He says that i schould get in with him and I say no my husband will come back any moment and I awake? Similar dreams with the same person happen often in dreams of 2 to 3 in a row...what gives???
