I'm with you there Farangbah.
I think the biggest change in my mindset over the past year or so hasn't just been my increased involvement with LBs, its been my increasing ambivalence towards relationships as a whole. Based on my own mis-adventures in that field and also dysfunctional relationships I've observed amongst my own friends and family peer group.
I've always been a little bit of a loner so I find the whole 24/7 nature of a relationship hard work outside of the bedroom stuff.
Valentines Day, Xmas and any social events that say +1 on the invite suck balls but apart from that I'm happy on my own and the independence, plus peace and quiet that brings me. Occasional contact with various LBs through Skype, facebook etc is there when I need it until that time I come back to LOS. Then, when I land at Suvanabhumi the fun and games begin again for that 2-3 week stretch....and then back home to the UK to normality. And then repeat ad nauseum.
Like you say, maybe in years to come the thought of dying alone without any kids produced might weigh on my mind, but as long as I have the money to travel to LOS then I will always have a "love life" of sorts.
