Worried about losing my identity after marriage

Two years ago, after ending an abusive marriage, I moved to a new country, ready to start a new chapter… I met somebody new and we’ve been together for a year and a half now. We’re about to get married next month, and I am so happy with him - he’s emotionally mature, supportive and is devoted to me. We come from two completely different cultures and countries, but manage to respect and embrace our difference…

We’re two weeks away from the wedding and I’m finding myself nervous - nervous about taking his last name, scared I will lose my identity and independence. He sees us coming together as a family unit and looks at it as romantic, but I come from a patriarchal society where women are forced to take their husband’s last name, forced to lose their identity and adopt their husband’s identity and family..

My fiancé and his family are modern in every sense but believe in the traditional idea of family and I feel like there’s an expectation for me to take their last name while losing mine..

Why does this scare me so much ? I love him and want to marry him, I have no doubts. But the thought of changing my name, taking his surname and losing mine makes me anxious and feel out of control… I know he will still love me no matter what I decide to do, but I’m feeling very stressed about this amongst everything else…
