no problem for me to leave every 3 month . the only pain in the ass is the renewal of WP every 3 month ( previously) . I travel alot and had never stayed in Thailand for more than 2.5 month. most of the time, I exit Thailand in about 1 - 2 months for short vacations. leaving Thailand every time (alone without me wife) is a jail break 4 me..
Not that I don't love me wife, some times (many times) you just need to let the birds fly..
