I've been separated for a year, going through a divorce. DH behaved very badly, he's an alcoholic. Married 20 years. Saw him last weekend because I took my DS to meet him. Ended up having a drink. He told me he loved me very much. So confused. He's living with his mistress. Not paying any of the bills he was paying but making excuses. Mistresses husband paying for rental of house. Poor sap. Should I contact mistresses husband to find out truth or would I just look pathetic? STBXH lying through his teeth as always.
