Do random nice acts
Though this is appreciated in all relationships, random acts of kindness will go far when you’re dating someone who is insecure. Leave her a vase full of flowers one morning after she goes to work. Buy him something that you know he will value and love to have. These random and unexpected acts show that you really truly care about the person you’re dating. The emotions these acts stir up will help make the insecurities go away in time.
