What would you do when your love life doesn't exist?

I have been married for almost six years. Before marriage was mind blowing well he was a nice man too hence we got married but soon everything declines. From having 3 to 4 times a week to once every 2 weeks then after a baby once a month now it has been almost a 8 months. I feel so lonely, isolated, rejected and ugly. I am I think on the brink of depression as I don't like the idea of cheating or divorce but what else do I have? I told him how I feel he came out with the right answer but do nothing!
