I have been messaging and talking to a married man for over 10 years, we generally talk about day to day life and check in with each other every single day aswell as sexting and videocalling. He has asked to meet me so many times and I have refused each time because my morales and beliefs are telling me not to mess with a married man, however he has told me his wife has cheated and goes out every weekend and gets blind drunk whilst he takes care of their children, he works extremely hard and cooks and cleans also, she has told him she won't change and he is free to leave if he wants to, he doesn't get any physical emotional support love affection or intimacy and hasn't for the last 3 years. I've advised him that maybe we shouldn't talk anymore and he should focus solely on his marriage but he says it's not me causing the problem. I don't know what this is if anything, should I leave well alone or should I at least meet him. 10 years is a long time to talk to somebody without meeting them. Any advice please?
