One of us is very social and the other is not. Does that work?

Yes, differences in social energy absolutely can work in a relationship, and often do. What you're describing isn't necessarily an incompatibility, but rather a difference in needs that requires open negotiation. The initial feeling of balance you experienced is a good sign; it suggests your individual preferences can complement each other, rather than clash. The challenge comes when these differences are left unaddressed and lead to unspoken resentments or a sense of always spending weekends apart. Instead of letting that happen by attrition, it's crucial to negotiate your social calendar explicitly. This means sitting down together, perhaps mapping out a typical month, and talking through expectations. You might decide which family functions you'll attend as a couple, and which social gatherings one of you might attend solo. Consider agreeing on dedicated time you commit to spending together at home, perhaps a specific evening or a Sunday afternoon, while also acknowledging that your partner might spend other times with her friends and you might enjoy your quiet space. This isn't about one person giving up their preferences entirely, nor is it always easy to find this rhythm. It requires both partners to be flexible and to genuinely understand and respect the other's needs. She needs her social outlets, and you need your quiet refuge. Finding ways to honour both, without either of you feeling neglected or overwhelmed, is the path forward. This requires ongoing conversation and adjustments as your lives evolve.
