A guy who is ghosting you may reappear now and then, but that appearance comes with a request. It will probably be a request he knows will be fulfilled by you. If you used to have sex, he might come around looking for that. If you used to send him photos in skimpy lingerie and he wants to see some new ones, he may ask for those. When he either gets what he wants or realizes he won’t get what he wants, he will fade away again. He may continue to try this whenever he gets bored.
It’s hard to admit that you may be being ghosted by the man you’re interested in. You may recognize the signs, but be confused when he pops up again. This is a common trait of men who ghost. They fade in and out until they finally disappear for good.
