Just wait, you'll find out 🤣
No but seriously, you're not always going to see eye to eye on everything. Perception is so subjective, too, which will mean that you might perceive a lack in some areas, or he might perceive a lack in some areas, and both or neither of you will be correct to some extent.
So then you have to negotiate that perception from an objective standpoint to ensure everyone's needs are being met and you might not have the capacity to give more of yourself.
Also, everyone likes to say marriages are 50/50, but that's the biggest crock of crap. Marriages are 50/50, 80/20, 100/0, and every iteration you can imagine. Spend enough seasons with someone and you'll see that energy levels, wellness, serious health conditions, mental health, workload, children - just about every variable you can think of - will alter the amount of effort you and your partner can put into the relationship and family more broadly. So then you have to learn to navigate a situation where you might be giving more, taking a broader view in the long term to make sure you're not just being perpetually exploited.
Marriages are practically complicated so they're going to be emotionally difficult. It helps enormously if you have similar systems of value in the first place, but none of us is ever identical. You'll rub up against friction sooner or later, and there isn't always an easy solution.
