(Replay): Leaving an unhappy marriage, Flirting, Toxic parents, Needy friends

In this replay of Ep 202, the questions are: 1. I've been married to a 90% disagreeable man for 42 years. Many times I've packed my bags but never followed through. I dream of being on my own, doing the little things in life without being questioned. As he has gotten older his drinking has become a problem. Every year finds me more depressed. How to know when to go? 2.why do men flirt? I am falling for a guy who is a huge flirt. I see him flirting with me and with other women, and he has a long distance, long term girlfriend who he is faithful to. Why does he flirt so much? Why am I falling for him even though I know he doesn't mean anything serious by flirting? 3. How do you deal with toxic and controlling parents who like to believe that they are doing RIGHT by continuing to control your life well into your adulthood ? Is it normal to feel that you have a hate relationship with your mother because of lack of support and love to you? As a daughter it feels awful to feel it this way but I can't get over the fact that having a distant and uncaring mother has driven me into agreeing to marry a person who is totally different to me in personality. Even to this date my mother still emotionally blackmails me to not get a divorce by using her health as a reason. You can divorce your spouse but how can you ever divorce your mother and get over it without feeling the guilt? 4. A friend of mine is having some troubles getting in touch with his friends regularly. He always thinks, if I (or anyone else) doesn't contact him first, I don't like him anymore. It seems to me like he is suffering from some kind of inferiority complex in that sense. How do you explain such a behavior in an evolutionary sense or to broaden my question, why do people suffer from inferiority complexes and how can they try to overcome such feelings?
