Men lost interest when they get used to it, and get bored if it is done repeatedly. Ask him what you can do to him to make him happy with you again, if the answer is negative, ask him what does he wanted you to do, even if it takes your heart to break it is better to know than keep you like that. If he wanted you to free him then the earlier the better, because it will come to this end anyway. Maybe he is just waiting for you to tell him first. I am sorry to say this but, you must think of this conclusion after he said he he can not put his feelings back again anymore..

Wake up lady..... let him go!
