Let's be honest about this, very few of us, if any, who are married to Thais are going to have a lot in common. In every long term relationship I had back in the UK, we always had a lot in common, ie the music we liked, the football team we supported, the concerts and clubs that we went to etc. In every relationship I had, being a professional musician meant that she came with me regularly to gigs.
Here in Thailand, I do not have anything like these with my Thai wife and we have been together now for over 16 years, still happily married, and I am a lot happier now even though we don't have all these things in common.
