Love and relationship

Okay my hussband told me it was over, he told me. Give him 2 weeks to think things thru. But its been over 2 weeks he has not said anything. To me we got in a huge fight on nov the 8, of this year he says I am fed up with you and this situation I cant anymore I think I want a divorce I plead and begged him to give me another chance. Here came his birthday nov 20, I spoke to him I told him dont say anything just listen… ladies my heart was racing so hard I couldn't find the words to say babe, give me a chance he said sorry Janet I cant do that so I told him give me chance to prove to you I will not check up on you, say any bad things to you, but he did leave he left to his friends house he came back saying I don't think we are going to work out but once again I told him wait let me show you I can change my ways. He said "ok I'll think about it, " will see at the end of the month if he will give me a second chance. "At this point I am given him all the space he wants and needs but why does he come back home, take a shower, eat here when I cook, and sleep in my bed knowing there is a sofa to sleep on what is going through his mind?. Last night he was here with me in the room but he wouldn't say anything he always comes back and just turns his back to me and falls asleep what shall I do?
