Boujac,I am a recovering alcoholic (4 years)and I am torn in what to put down.
As aguy I say to change the locks and get your support as chances are he cheated
On the flip though I know what its like to be there and sometimes its easier talking to some one on the outside ,
My heart is saying change the locks and salvage the rest of your "prime" years if he is acting like that ...but thats my opinion you have to look deep inside yourself and ask yourself if I was in his shoes what would i be doing in that room with that woman and that should tell you what to do ...be honest with your self when you look within
God grant me the serenity
to accept the things I cannot change;
courage to change the things I can;
and wisdom to know the difference.
