How will caregiving for my in-laws affect my husband and i's relationship?

It depends!: If your relationship is strong to start with it has more likelihood of being strong when you are care-giving. It could bring you closer together or create negative stress that could pull you apart, i think you and your husband should discuss all the angles before you decide on the best course of action. Good luck.

Caregiving: for in-laws is commendable. The most positive outcome is that your husband and family will be grateful to you. a negative possibility is that you will feel taken advantage of. You need to be in touch w/and clear w/your feelings. Good communication w/your spouse is essential. Also, please get some respite from you work, i.e., take a break. Peace and good health.
