I Am A European Mystery

Side 1 says... I have been with my live-in boyfriend for almost three years. His name is "Lukas". Lukas was born and raised in Germany/Austria. He has been living in the US for 17 years. He has a Mother and a sister in Germany and has not told them anything about me besides the fact that I am "a good woman". He began the relationship by telling me that I would be a secret because He is going thru a divorce and did't want them to think I was the cause for the divorce. I understood that at the time, but THREE YEARS?? Derek speaks to his family quite often (on the phone) & visits them for 2 weeks once or twice a year. He does love me very much, this I know but I would love to speak to his loved ones on the phone and meet them someday. I am a very family oriented person and feel left out of the most important part of his life. His sister can see me on his facebook as a love relationship but I still feel left out. Am I being too pushy?? I have a great 14 year old boy. Lukas treats like a son of his own and he is great with my family. Should I force the issue or be more patient because Lukas is worth it? I choose my battles very carefully. Thanks for your input.
