Boyfriend hidding pregnancy from family.How would you feel?

Ma
Im 13 weeks and just had my second ultrasound on the 16th. My boyfriend refuses to tell his family that im pregnant. First he said he will do it in April and now that we are nearing the time now says he isent ready. Im very excited. I feel like being "hidden" is really hurting my self esteem. Like why am I not good enough? Whats wrong with me? Its driving me crazy. His only explanation is that is family will give him a hard time. But i really dont see that being the problem. They are super close. How would you feel? I dont really have any family or friends so no one therefore to talk or bounce ideas off of. What do you think? By the way the is the first grandchild to be born and his first kids. Please be nice and let me know what you think.
