Wedding gift dilemma?

Looking for some people’s thoughts on this.

My fiancés dad has offered to contribute to our wedding, just like he did for her older siblings’ weddings. However, I don’t want to accept it and feel we should pay for everything ourselves to stay independent.

I understand his perspective but worry that refusing it might seem disrespectful. I was more or less raised not to accept hand outs plus I wouldn’t want my parents feeling bad if they found out thinking they needed to give large amounts of money.

EDIT: Thanks very much everyone for the responses. I appreciate it, great answers and makes me feel a little bit better accepting it haha
