Paralysed by fear + Mounting Pressure

I have been with my boyfriend for over 3 years. Due to cultural reasons, I have not been prepared to broach the subject with my family and they don't know that I am in a relationship. This has troubled my boyfriend and caused a lot of conflict between us. I know that my family will not accept the fact that I'm in a relationship and I am very frightened to tell them. I feel scared that things between us will not work out and then I will have damaged relations with my family. I'm also a bit of a coward and a people pleaser and I don't want to disappoint. My boyfriend has been largely patient but recently he has laid out an ultimatum (though originally it was my idea to have a date to work towards) - a deadline of this summer of at least mentioning the idea of him to my family. I have felt very pressured in the past.I'm scared and I don't want to do it but I see where he is coming from. Now he has started learning the language of my family, at first I just thought he wanted to learn the language but tonight he told me that it was so that he could make a good impression. I can't deal with this, I made my excuses to end our conversation. It's too much pressure for me. Can anybody offer advice?
