If your date is always on their phone or looking around, they aren't truly present. While it could be for a valid reason, lack of explanation may be a concerning sign.
Your date being late without informing you. Being caught up is understandable, but no communication may signal disrespect.
Love bombing may take weeks to become apparent, but manipulative individuals might overwhelm you right from the first date. Stay vigilant.
Beware if your partner obsessively mentions their ex(es), as it may indicate unresolved feelings or bitterness. Watch for excessive criticism too.
Trust your gut! If uneasy or can't explain the feeling, escape the situation ASAP. The gut is like a second brain in mental health.
