It’s important to understand why your gardevoir is doing this before you can reach a resolution, anonymous. As you likely know, gardevoir are highly loyal pokémon, and thus, they possess a natural instinct to protect their trainers from any danger. When their trainers are pregnant, gardevoir will be especially adamant about protecting them, as it’s no longer about protecting just the trainer. Rather, it’s also about protecting the trainer’s child, which gardevoir perceives as being too weak to survive on its own—meaning gardevoir believes your baby needs extra protection, even if it hasn’t been born yet. In other words, at the risk of putting it too bluntly, your gardevoir sees everyone around you as a potential threat or an inadequate guardian. This goes especially for your husband. Your gardevoir may be attempting to judge whether or not he’s fit to be a father—or she already has, and the answer is no. Either way, as difficult as it may be, your main task here is to convince your gardevoir that: A) you’re doing all that you can to ensure the health of both yourself and your baby on your own, and B) your husband will be a competent father.
The first point may be the easier one to prove. Show your gardevoir that you’re capable of managing your health, attending the requisite doctor’s appointments, following your usual schedules, and so forth without her assistance. This isn’t to say you should make it clear that you don’t need her. Rather, the goal is to make every effort to reassure her that you and your baby are and will be fine. Sometimes, all it takes is to ask her to step back and watch you work for a day before she understands. Other times, you may need to keep up with this for a couple of weeks and insist on doing as much as possible yourself until she finally gets the idea.
Of course, if your gardevoir’s behavior is so extreme that she prevents you from attending doctor’s appointments, then it’s fine to be firm with her from the outset. Establish that it’s necessary for the health of your baby for you to interact with others, and try to explain to her that going to the doctor is a lot like seeing a Nurse Joy for her. Emphasize your baby’s needs, and she should be able to relent at least that much.
Meanwhile, the second point will likely be more of a challenge, as getting her to allow your husband to get close to you is an entirely different story. They key is, really, allowing your husband to do little things around the house. Allow him to take over cooking, cleaning, caring for your gardevoir, shopping—as many household tasks as he can shoulder. Have him show an interest in the baby by coming up with possible names, constructing a nursery, purchasing items you’ll need when the baby is born, or simply accompanying you on your appointments (once your gardevoir is more comfortable with the idea). The more he can show that he’ll be a good father, the more likely your gardevoir will be willing to listen to you. I say “will be willing to listen to you” because when it looks like she’s warming up to him again, that’s when you should tell her firmly that your baby needs their father (and family, for that matter) as well. Again, emphasize the baby’s needs, rather than your own, to appeal to your gardevoir’s current priorities.
Best of luck and congratulations on the upcoming addition to your family!
