My ex saying he’s going onto a treatment program through the hospital for his drinking doctors are going to write a letter for a referral. This is 3 rd time of leaving him and I don’t wanna go back to him he’s let me and my son especially down for nearly 3 years now and I think that’s enough time waste. But he’s always lied in past to get me back and it worked but I feel like this time I need to stick to my plans of not taking him back. What shall I do though?
