Well I want to start off by saying it doesn’t matter how much you love someone or how good you are to a person its hard when the person has problems that they are unable to deal with but not willing to change but tell you they love you and will do whatever to keep you but its all lies
I feel you. I am in the same situation. It doesn’t matter how much I helped my ex financially and emotionally, he still left me for his ex girlfriend. He said he still loves me, but it’s all lies
