I'd love to hear everyone discuss this so called "Lifestyle" in detail of how it has affected your lives. 
One month ago I proposed to the love of my life, my girlfriend of two years after almost two months of being apart from her.  I had broken off the relationship not as to avoid her or to see someone else but to work on my issues she had been complaining about for some time. This I did do and continue to this present day. After intense self work, therapy, and Alanon support I realized I still loved her and wanted to spend the rest of my life with her. After Christmas I got back in touch with her and  we were back together in a matter of seconds. We both shared that we loved each other and life was good.
After two weeks of being back with her I proposed.  It was late evening on a Monday. i got down on my knees and asked her hand in marriage and she accepted and quickly placed a ring upon her finger. We were both elated. Not for long!
On the following Wednesday she had us sit down to discuss our relationship and the realities of us joining our lives together. She has two children from a previous marriage and a home she is indebted too. Topics of this nature were not what was on her mind. She then proceeded to drop two bombs on me from which I'm still in recovery. Bomb number one; She explained that during the interim we were apart she had been involving herself heavily in the swinger lifestyle. she also mentioned that it opened her up to "growing" as a person and that she wanted to go into it even further. The second bomb: She mentioned that her age, 40, and already having two kids that she was adamant about not having anymore children, meaning with me. She explained that it was too hard on her body and that she couldn't risk it for herself and for her children. She knows very well how much I want a child of my own and want to have one with her. She explained that she "can't" have children but has had an IUD surgery to prevent one.
After hearing her share her desires and concerns at least intellectually I shared my concerns with her. My intellectual side, I discussed my concern with her being a swinger,the incredible risk of catching a permanent or life threatening STD such as herpes aids, clap, gonn.etc. Also the rampant drug use especially alcohol, cocaine, meth (xtc) and possible problems with intimacy with me and jealousy that can arise within that community and possibly coming in contact with dangerous people that take advantage of women in her situation. 
Later in the night whilst in bed my soul and heart digested what she'd shared with me and resulted in my having a panic attack, and have had two since. I've never had a panic attack in my life and sleep like a friggen log. the next morning as you can imagine we got into a fight. I told her that I couldn't, at the moment, even understand or accept her choices. she immediately became verbally abusive with me and her children. She was very confrontational with her justification of her sexual promiscuity going so far as calling me a racist and a homophobe. Which are plain not true and designed to be hurtful towards me. 
After the worlds shortest engagement, she texted me hateful messages and said she'd return the ring by leaving it on my porch. Respectful? Hardly. The next day she reneged on her promise and left the ring on her porch for me to pick up. Two days later I did pick up the ring and left her a letter explaining how I really felt. Against better judgement I also wrote within the letter that I thought she might be suffering from sexual addiction and attached a 6 page description of the symptoms  of the illness. It would not fall on deaf ears as she is an LPC with a masters in psychology.
Upset from the letter and what had happened she texted me a threat that if I contact her in anyway that she will call the police. That is the last contact I've had with her. I know she is suffering and it hurts to know I can't help her in anyway. I pray for her everyday that she feels the love God has for her and that she can open her heart to God. 
The lifestyle has taken away from me the love of my life. To all of you reading this please share your stories if this affects you in anyway. There needs to be much much more information about the effects of this swinger culture that is growing in the U.S.A. and Western Europe.
