Stop playing the role without the title/benefits: When you and your ex are dunzo, you already know the dangers of â€œhooking upâ€ on occasion with no titles or commitments. Youâ€™re bound for failure, resentment and feeling some type of way. With work, you have to put the brakes on doing your job behind the scenes. When former co-workers call and e-mail asking for help with how you did your job, you must politely decline. That is no longer your responsibility.
