So lonely.

A few months back my SIL needed a favor and asked if her oldest son (23yo) could stay with us since we had an extra room and she didn't have enough room in the house. She is amazing to us so I didn't really hesitate. But now I'm regretting my decision because I just feel 3rd wheel in my marriage. My husband and I literally have no private time. We used to even run errands together and that was enough alone time together. Now we have absolutely NONE. Nephew has to go with us everywhere. I'm currently almost 33 weeks pregnant and I feel like I'll never be alone with him again. Idk why but every time he leaves me I just wanna bawl.
