Missing my fiancé and feeling lonely

Melissa • Due with baby girl in July!
I'm head over heels in love with my daughter but every night since we have come home I either need to sleep in my step daughters room when she isn't here or the couch because my daughter won't sleep unless she's in bed with me and my fiancé moves too much to be in bed with the baby. I just miss him at night and feel lonely sleeping away from him and not in my own bed. Any tips to get her to sleep in a bassinet? It's making me so sad.
