I would also like to add that I have asked a couple of close friends and the sister I am on speaking terms with for advice, and they all say I'm a great guy and they don't know why women keep doing this, and there are plenty of great women out there who don't cheat... so I ask if they know anyone they could introduce me to, and they've all said they don't... even though they have set other friends up (with varying degrees of success).

It is starting to really feel like there is something about me that people view as... i don't know... unworthy? I'm almost 40, and I don't want to die alone... let alone spend another 40 or so years alone and never knowing why.
