Why hasn't he been staying with me?

Fiancé hasn't been staying with me lately. He used to stay atleast 5 days out of the week he's only stayed once this week and didn't even come see me 2 days this week. Am I being too emotional? Are the pregnancy hormones getting to me? It wouldn't be so bad if he's actually busy but he just goes to his brothers or parents house.. Is this what it's gonna be like when we have the baby.. 😔😔
