To accomplish a successful phase out, the phaser (person performing the phase out) must evaluate the relationship with the phasee (person being phased out) and arrive at an appropriately paced schedule. No two phase outs are exactly the same, because all relationships are different, but luckily they all use similar steps. The basic rule is to gradually reduce contact (phone, IM, physical) but not in huge jumps. Over the period of two months almost anyone can be phased out. When it comes to the actual breakup, it will often seem so natural to the phasee that they feel it was their idea.
