My parents are such a mess.
What a shame. I am so sorry. I am sorry for your childhood and your mother as well.
Hi, there...wow, you really did need to vent! It is a shame, really, you're parents are still relatively young. I say this as we are in our early '50's and still feel very young at heart.
I've always believed that the gambling addiction is the worst of them all, because when it's all over...loved ones are not only left to grieve, but their lives are often left in utter chaos.
What I would do....regardless of whether it does any good or not, but I would tell dad, look, you're dying, at least give mom some peace for once in your life before you go. He is probably so afraid she will leave that he puts her down and trashes her self esteem so she won't think about going anywhere. But it would be a shame if he died
