Dear Prudence,
I love my husband. He is a stand-up guy who always tries to do the right thing, but right now, we are arguing about what that is. I am currently pregnant and have a toddler. He has a 6-year-old son with his ex (they were never married). She has been unemployed for a while and is facing eviction. Obviously, my stepson can come and live with us full-time. The problem is his 12-year-old half-sister, “Mia.” His ex wants Mia to come live with us so she can stay in the same school district. “Temporarily” until she gets on her feet.
I am completely opposed to this. One, we literally don’t have room for me (we have a three-bedroom apartment). Two, our finances are already stretched thin as it is. Three, my husband has no legal rights to Mia. Four, Mia has been openly hostile toward me and my child, the few times we have interacted (her mother hates that my husband married me and not her after she broke up with him). This has disaster spelled all over it.
My husband wants to “try it” for the summer, meaning the care of Mia will fall on me since I am a stay-at-home mom. I am this close to packing my bags and moving in with my mother. Mia has a father who lives out of state and grandparents on both sides. They might not be the best, but it isn’t like she or her mother would be sleeping on the streets. Maybe this makes me a horrible person, but I already have my hands full as is. This is too much to ask. How do I convince my husband of this?
