You could ask the same question; 'are you bitter about Thai women' that could unleash the floodgates!
Divorce can be bad, but I think for quite a largely unreported number we get through it OK.
I'm still very friendly with my ex, mother of two of my kids, we talk several times a week, and she gets on great with my Thai wife, primarily because when they are together they love nothing more than to bitch about me!
How many stories have we all read on AN from bitter guys who got fleeced by their Thai gf/wife?
So relationship breakups are always hard, but I think the bitterness comes from the degree of, and I hate to say it, the money that gets lost.
Me and my ex did a mutual separation agreement, never needed a lawyer, we filed it with the court it cost us $50 and six weeks later it was done.
Neither of us got all that we wanted, but it was fair and we got on with our lives
Pretty sure Bitterness=Money
