I've been in a loving relationship with an abused married man for seven years. He tried to leave his wife for me once but the result was catastrophic; he had a breakdown. We weren't able to communicate for over two years, and then finally got together again over my daughter's health (as well as being the love of my life, he is my oldest and best friend; we've known each other since childhood). All our meetings were secret and he took enormous risks to see me & the children whenever possible. However, he could not, or would not, make love to me. Not so much for moral reasons but rather out of fear. So I've not had sex since 2011. He suddenly ended the relationship entirely several months ago. I'm heartbroken, devastated and hope that this abrupt separation will give him the courage to leave a physically and emotionally abusive marriage.
I'm well into middle age and miss having sex. I'm not at all interested in a new relationship but I'm worried I'll never have sex again. I haven't dated since 1993. I know nothing of dating sites or even tinder, which frankly intimidates me. Can anyone advise me?
