From lovers to roommates

Our second baby is on the way. My husband was forced to sleep next door with our toddler simply because we don't fit in our bed. Plus my toddler moves alt while at sleep which makes it unsafe to sleep with her while pregnant. Ever since we sleeping separate room, I feel like the intimacy got lessen and lessen. Intimacy became a task, just for the sake of doing it. We talk still, but there's no connection. I feel less and less updated with his life, his goal, his feelings. I keep thinking its a phase, or maybe my hormones are just acting up. But I feel so far away from my husband though he is just next door. I love him so much. But sometimes I just feel less connected to him. Every time I plan something fun, I don't think he finds it fun. He is so focused on work, work and work. I don't know if this is how marriage is supposed to be when you've been married for 10 years. It makes me feel more alone each day.
