Hi Ben,
I wanted to thank you for sending me a good morning greeting every day. You are thoughtful and a sweet person. I would like to change the way we are dating. I know it is a Thai custom or old tradition to bring people along on dates. I have dated a number of Thai women and you are the first one to bring friends or family members along on a date. Westerners do not date like this. You date some one, if you like them after a few dates you will introduce them to your friends, and if you get to really like them then you introduce them to your family.
It's your country and I respect your customs. In the time I have spent trying to get to know you I have learned little about you. I tried getting to know you better by email but you were not writing much in return and had no questions for me. If you were really interested in me you should have lots of questions. I come from the other side of the world where things are very different so lots you could be curious about. When we meet we have a language barrier to over come and with other family members there it is difficult for just the 2 of us to have a conversation. It would be rude to ignore your sister and nephew and when trying to include everyone in conversation you and I being able to talk to each other winds up being very difficult and we talk very little. If we all spoke the same language there would be no problem we could all talk together and I would still get to know more about you.
If you want to meet and talk to me again and have a bite to eat I would be happy to meet you. I want the opportunity to be able to get to know you better but that can not happen with other people there. So if you want to meet by yourself and try to talk great. If we have a hard time we can laugh about it. If it does not work or it is too awkward or difficult we can just give up and go our own different way.
So it is up to you if you want to meet again.
