Yes I believe that’s what hes doing. He’s lying to see if you reply. Don’t answer him because I don’t think he wants to be back with you for now. He wants to know if you are still willing to hang around. If he wants to be back Im sure he will specifically say the magic words.
I suggested my friend not to reply to her ex and in one text he did say he was willing to change for her and that hes sorry. Of course my friend decided to be in another relationship instead but her ex said those things without hearing from her.
