Looking to meet a best friend with benefits for long term relationship

My Ideal Person I'm an attractive middle aged guy. As my ad states, I'm married and lonely. The romance in my marriage ended years ago. Please don't ask why I don't get divorced. I have my personal reasons for now. I'm looking to meet someone that may be in a similar situation for a long term relationship that could become life long some where down the road. I have pics to share. Please respond if interested.
