I am 40 years old and have been married for 15 years. recently i have been having an affair with a woman who is 22 years old. I cannot stand my wife or her stepkids anymore. all we do is fight. she keeps my life under constant supervision. my kids snitch on me whenever i do drugs, unfortunately i am addicted to narcotic painkillers. my girlfriend wants me to run away with her but i feel that i cannot just leave my wife in this situation. i am worried that ii will never be able to have fun again for the rest of my life if i stay with my wife. i cannot smile or be happy around her. my girlfriend wants to have my baby and makes me completely happy and satisfied. my wife says she will kill my girlfriend and my dogs if i ever talk to her again. she is my best friend. it is not about the sex. i am miserable, my girlfriend is going to be moving away soon and wants me to go. i fear that if i don't i will have no choice but to end it all. any help greatly appreciated.
