Divorce...

Did anyone know that their marriage was falling apart... Try to fix it and nothing worked. My last option is divorce. I love this man more than anything but he runs off when things get tough. He has been staying at his parents hours away for the past month. Before that he ran off to his parents for 2 weeks in November. He has had a drug problem in the past but got sober and i think he relapsed. I havent heard from him in a week. A week ago we talked an he said he was moving back in next weekend which will be in 4 days... But then nothing... Did anyone get a divorce even though you still loved them more than anything... Did you regret it? I need advice...
