Every guy always resorts to "wants to bone". But what if its deeper than that?
I have a lingerer, who will always reach out to me after every failed relationship. I believe its a mix of things, you feed his ego, he finds comfort in you, he still isn't 100% over you and wants to try with you again or he simply wants to bone like every guy in this forum would say.
