I'm mid 40s, been married for 20 years, and honestly this shit came up about 8 years ago too and then dissolved. Now its come up again. I'm a beta bitch and a nice guy and always been one. I had a serious girlfriend before meeting my current wife and when my girlfriend and I broke up, that was probably the only time in my life I was remotely alpha. I pulled ONSs and didn't treat women very well. Problem was I was drinking and doing a lot of drugs, having unprotected sex, and way too many times worried about STDs or pregnancy scares. When I met my current wife I was ready to put that shit behind me and settle back into the comfortable nice guy ways. We just had our 20 year anniversary and my wife brought up our age and how her beauty is fading, and when it's gone, it's gone, and now is the time she wants to experiment before her opportunity passes her by. Problem is I just don't want to do that shit. I know I need to quit thinking about her and what she might do and instead focus on myself. Lift and hit the gym (I already have been doing this for years, but I workout in my home gym), lose weight, dress better, get some hobbies outside the house. Emotionally I'm ready to blow this shit up (state boundary of filing for divorce if she wants to pursue other guys, open separate bank account and direct my paycheck into that and start managing bills) or would it be better just to STFU and work on myself?
