My husband worries to much

My Husband of two years has a bad habit of asking me on a regular basis if im okay, is there something wrong? Do you love me?...I on the other hand of love the attention but sometimes too much is too much...It leads me to believe if he has done something wrong. What do you think ..... He is the best thing that has ever happened to me compared to my past relationship....Although Its a little embarrassing to admit that when we first got together my husband was going through an annulment as well as the fall of his buisness which led him to work an awful job selling passes to mainly drunken slobs that wanted to party at top of the line night clubs to make ends meet in hopes that the recession will pass and he can start making a descent living again..You can see it in his eyes he was miserable, He pretty much lost everything he worked so hard for...Unfortunatley it broke him down in result broke his spirit and broke his heart. it was just getting harder and harder. He also felt like he was letting me down also....But the way i See it he did what he could. he then began drinking and would get violent with anyone and everyone including me....However he realized in a short time that he was hurting the one he loved and we were expecting as well and he completly went cold turkey and quit he moved us to a different state and has been completely sobber and never raises his voice at me. He is patient, fun loving kind and very considerate....Kisses me good night tells he loves me everday...He provides for our family and he puts us before him. He even goes as far as to apologize to me every so often for the awful person he once was even after I have forgotten that he was once an alcoholic He is a totally differnt person sobber and drunk its been almost two years....
