Thanks all, many great replies and lots to think about! I am clearly not happy just having my immediate family as the only people in my life. Once and a while I get together with some of the guys in the neighborhood as well which helps. The trouble with neighbors is they come and go. We have one set of friends that believe they'll be moved out to another city (military), another with a hose for sale sign and yet another going through a divorce. Not only that but if we want to have a second child (which we do), we will have to move away as well as the house is not big enough.

I find it really difficult to make meaningful friends. Not sure if its because I rub people the wrong way due to being shy or not but i'd like to improve that.

I also don't understand why this is an issue for me now. I think when I first started dating my eventual wife, I just cared about her as I was happy to have found a girlfriend that understood me, etc. Maybe this is me now looking for new people to share things with? Not really sure, but I do find it odd that this never bothered me for the past 5-8 years, but this year has really done a number to me.

Thanks all.
