Where do people go for Refuge from loneliness and the lack of physical human interaction?

'll be the first to admit, I am very fortunate. I went to college at a time when you could get full academic scholarships. I also went to a part of a prestigious school where there would be around 16 students all through my bachelors, masters, and doctoral program. The first huge class I was in was one I taught (as a teacher's assistant). I'm 50 years old and I still have my mother nearby (10 miles only) and can help her with groceries and such. I have two wonderful children, and through a few 'stumbles' have come to the realization that I am not my possessions! (That was a difficult one!)

The difficulty is adult interactions. I am a special needs teacher in a very urban area. I have always been an avid reader and a writer. (In the past, I've published nonfictional peer review articles, and fairly recently been able to publish a few non-fiction short stories & poems). As wonderful as these 'accomplishments are, they are solitary endeavors.

Sadly, for her, my wife's life centers on her. She is addicted to Second Life and give little or no attention to our children. (As an example, my 12-year-old daughter had me purchase her bras, feminine products, and even told mewhen she got her period. (Of course texting her friend;).

Although I formally studied literature, I can get into anything someone had a passion for, so my interests vary from Mallala to Tom Waits, to Counting Crows, to politics... while my wife's interest is in Second Life.

Honestly, I'm lonely. My skin hungers for a touch. (I'm 50, so I hope you realize I'm not talking about sex.)

What do people do here that are lonely? What suggestions do you have? The Internet is a saving grace, but it doesn't take the place for human interaction. Please do not confuse the idea that I am lacking in sensuality and intelligent discussion with 'sex'. While my skin hungers for the touch of another, and the idea of being held and just being told that I am 'good' is one of my fantasies. Sex, and physical appearance, are affected by age. Sexual desire, is affected by not only age, but the medications we take as we get older. Although sex, and sexual fantasies are a distraction, it's like riding a swing, you don't end up much further than you started off! ;)

I hope this finds everyone well and at peace. I hope this doesn't come across as a 'sob' story. I am surely blessed with good fortunate.

TL;DR - I am 50 years old with a wife and two kids. Wife is addicted to Second Life and shows no affection and barely communicates. I am very lonely and wish for physical, human interaction.
