Plan dates with her

Get him to set the ground rules
Some friendship are geniune, whilst others are written sinister all over them. if the friend has a ‘man stealing’ behavior like calling or texting in the middle of the night, then it’s your man’s duty to put her in a place if he respects you and the relationship.
Give the friendship a chance
Try approaching this as calmly as possible, be yourself. If you immediately have attitude towards her chances are you’ll start seeing things that aren’t there.
