I could be mistaken, but I agree with someone who says you have grounds to file for divorce. A spouse duty is to provide support emotionally and physically. If either party has failed miserably, your application will be heard.

Having said that, you need not fear embarrassment should it become known among family/friends if that is the outcome of it. Some remain in a failed marriage simply to avoid the stigma of a divorcee. Fret not. Your happiness is a priority. If it can't be found where you are now, move on.

But know this. That should be your last option upon exhausting all avenues to improve it.
