3. Your partner is afraid of talking openly.
If you’ve noticed that your better half is being shady and has started checking your phone instead of expressing their feelings openly and honestly to you, this could be a sign that they’re actually hiding something.
Either it’s just simple nonsense or a real act of cheating, you can only find out if you ask them directly what’s going on. A worthy partner won’t refuse your invitation to talk and will be open to discussing whatever comes up in your relationship.
