How do you convince someone youre dating the wrong person?
Express what you want to talk about. Share your feelings about the situation using “I” statements that convey your own observations so that youre not putting words in your friends mouth or telling them how they feel. State any observations (not judgements) youve had about his relationship and/or partner.
How do you tell your friend their partner is toxic?
Being direct and honest about your thoughts on the situation (when they want them) will make your friend value you you more for caring and looking out for them. Tell them truth about what youve seen about their relationship, and give them helpful advice and support, without overstepping boundaries.
