Hmm this story has a few similarities with my exH - he has been visiting Thailand frequently on business since 1993 (just after we got married). I went out there with him once in 1994.
DS1 born in 1996, DS2 in 2001 - not much sex after DS1 tbh.
Once very early on in our marriage he came back from Thailand and said he wanted to open a bar with a woman he had met there (just friends ).
Then a he had photos of a couple of Thai women he had met with another colleague and they had all been watching football in his colleagues hotel room!!
As far as I know he is still in touch with the woman he was watching football with.
By abt 2002 I was regularly hacking into his email - found that one of his mates had provided him with viagra. His mate had described them as 'sweeties' and initially I thought he could be taking anything!!
When challenged he came up with similar that he thought it would revive our sex life
Events above contributed partially to the breakdown of our marriage. When he came back from trips he was always very very grumpy - once said the only place he got 'respect' was Thailand.
The last time I hacked into his email (about 3 yrs ago just before we split I found that he was still in touch with the football girl and that he was looking forward to seeing her for some 'fun'.
He always swore he was faithful to me throughout our marriage but he certainly did not want to have much sex with me and I often wondered if it was because he was shagging someone over there. However I kept trying to rise above the stereotypes of that country etc etc
Fast forward to now we split in 2006 and he is now with new DP and has more children. Still regularly goes to Thailand on busines.
Hmmmm
Writing that down makes me wonder why I stuck with it so long
