I was hoping this is the best place to get answers to my questions for peace of mind. I had been trying to search the internet for a long while, finally, I think I am in the right place. I am at mid 50s, just lost 2 great relationships in my entire life and was scared to fall in love again but lately, I felt different to someone I met in a gaming website. She is in her mid 20s. I felt too old to be dealing with her moreover, she has an extra ordinary sexual behavior. She informed me that she gets pleasures from phone sex, cybersex, with someone physically and sexting but claims that she doesn't sleep around. We have unstable relationship because it's hard for me to read her mood. We talk in the phone and text frequently, sweet then all of a sudden her mood changes which most of the time leads to argument. I would like to pursue and keep this relationship. Am I crazy to deal with someone who is over half of my age yet have unusual sex appetite? I love her the way she is, she doesn't have to change her sexual behavior but I wonder if her mood swings which sometimes irritates me is due to mental disorder? Reaching out for answers, I truly appreciate any feedback.
