I'm the same age as you, lost...you're never too old to find happiness. My partner and I take a walk every evening, holding hands and having a lovely time. Sometimes I can't believe how lucky I am to be with someone I love so much!
Maybe it's time to give your husband some ultimatums...and if he doesn't comply, I guarantee there are other people out there who will love you and treat you with respect. Being with a drinker who throws your mutual assets into a slot machine and accuses you of lord knows what is not necessarily your destiny. Take care...
