My ex-boyfriend sent the wrong message to test me. Why?

Maybe he wants to make up with you, but he cares about face and doesn't know if you still have feelings for him, so he sends you a short message that looks ambiguous with other girls to see if you will be jealous, or maybe he wants you to know that he is still very moist without you, which is also a performance of love and hate. This is enough to show that he has not been able to get out of the breakup. In one sentence, it is' he still wants to entangle with you'.
