Recognizing the signs of emotional instability early on can help you better understand the situation and make decisions that protect your well-being. If your partner shows these 17 red flags, they may be emotionally unstable, and it’s important to assess the health of your relationship.

1. Extreme Mood Swings

If your partner’s mood shifts rapidly from one extreme to another, it could be a sign of emotional instability. One moment they’re happy, and the next they’re upset without warning.

These unpredictable changes can make the relationship feel volatile and unsettling.
