4. Rip off the BAND-AID
For the conflict-averse, a tempting alternative to ghosting is the slow fade. But honestly, this is just as bad as ghosting. Some would argue, even worse. Maybe you think that if you keep saying you're busy or canceling and rescheduling plans (only to cancel them again), she'll eventually get the message and give up. But when a woman likes a guy (or vice versa), hope is clung to no matter how faint. The slow fade only prolongs the confusion, drags out the pain, and keeps her from getting the clarity she needs to get over you and move on.
Ghosting and the slow fade leave the door open for you to come back into her life and haunt her again. Not fair.
5. Be clear from the beginning
If you have a history of ghosting and know you don't want anything serious, you have a responsibility to share this information early on. That way she can make an informed decision about whether she wants to get involved with you. Unfortunately, many women -- myself included -- will hear this and think that we can change your mind, or that we'll be the one to make you want to settle down. But that's on us. The fact that we saw it coming will make it not hurt.
