Is it normal to be attracted to your brother-in-law?
Mostly.Normal for most people
Yes, it can be normal to feel attracted to your brother-in-law; feelings can show up without you choosing them. What matters is how you handle them, since acting on the attraction could hurt people and complicate family relationships.
Attraction doesn’t always arrive with convenient timing or a sensible guest list. You can find someone appealing without wanting to disrupt your family or do anything about it, and having the feeling doesn’t make you a bad person.
People differ on whether they’d confess or pursue a crush like this, but most would be cautious because the fallout can reach your partner and the wider family. If you want to keep things uncomplicated, stick to clear boundaries and give the crush some space to fade.
