Here is my story. My husband and I are in early 40s and we've been married for about 17 years with two little kids. Most of time our marriage was fine except we didn't have much sexual life. In April of this year, my husband told me that he wants a divorce. He claimed that I didn't love him at all because most of time I didn't want sex with him. We are lack of initimacy. He was too frustrated about so many times when I rejected him for sex, so he decided to give up. I was so shocked. I agreed that I'm low interested in sex but that does not mean I don't love him. Actually I was trying to imporve myself. I know I loved him very much, and I did almost all the house work and take care of the kids. But he couldn't feel my love because I am a low sex driver. I admitted that's my problem. Since then I promised him I can make changes, and we also tried marriage consulor once. I even tried to initiate the sex with him. But he rejected everything. He doesn't want have sex with me any more, and said it has been too late and nothing I do can change his mind and soft his heart. When he said he does not love me any more, it hurt me so much. We are still living in the same house but in a seperate room. He closed the door every time when he was in his room. He even went some other cities by himself and didn't tell me where he went, leaving only me and our kids home.
Before I came to this forum, I did so many wrong things, such as crying, begging him, chasing him around the house, asking him to giving me another chance... but nothing worked.
I appreicaite it if some one here can give me some advices. Do I still have a chance to save our marriage? I really want ot save our marriage. I think other than the sex issue, we are good couple. I couldn't get to sleep every night, lost more than 10 lbs, and feel so hopeless and devastating now...

Is there any other things I can do to save our marriage? Not only for myself, but also for my two lovely kids...
