Although it is a good sign that he wants you to meet his family members as it shows he wants to internalize your person in his life more and more but there should be no element of forceful bonding.
If you feel he is too imposing and just pushing you into an uncomfortable position where you are not your own self, you better step back. Marriage means understanding each other and not imposing your opinion on the other.
If you are not getting along with the family, your guy should understand this and not pressure you into bonding with them.
