Is it normal to fall in love with your cousin?
It can happen, and having the feeling doesn’t make you bad or strange. Whether acting on it is wise depends on your ages, family dynamics, and local laws.
You can develop feelings for a cousin through familiarity, closeness, or simply the same mix of chemistry and timing that sparks other crushes. People vary a lot in how they feel about cousin relationships, so it can bring up strong reactions in families and communities.
You don’t have to blame yourself for a feeling, but take care with what you do about it. Respect each other’s boundaries, consider the effect on the wider family, and check local laws before pursuing anything—rules vary. If either of you is underage, keep clear boundaries and involve a trusted adult if you’re unsure what to do.
