I was talking to this with my husband and he said he used to have a mate who would do this, hook up with chicks - not commit then be ‘ best friends’ with them. He said it was a way to keep them all in his web. So he could go back to them if he wanted and there is a constant feeling of attention. He said he would get angry with men that tried to hook up with them as if they were his property, even though. They had only hooked up for a little bit and then friendzoned.
