This has a long back-story, so I will try to sum it up.
I never really met my whole biological fathers family (or really knew him) until I was almost out of college.
My mom, never married him, but was recently divorced (still using) my older brother's dad's last name. They stayed good friends, and I by default, got his last name. Unfortunately, the man who I called "daddy" passed away very unexpectedly a year after finishing my BFA.
My mom also remarried when I was in middle school, so I also have a step dad.
I have made a lot of effort to be around my biological father, and my several brothers and sisters from him; and he made a huge deal at my older sisters wedding about being a large contributor when I get married.
I chose, in the fall; to allow my step-father to walk me down the aisle. Since then, my biological father; who is very distant, and puts in very little work to our relationship, said he is very happy my step father is walking me; but now, after making a huge deal about funding part of the wedding; has said nothing.
Myy mom/step dad, aunt, and my fiance's parents have all kicked in, as well as the two of us spending a lot on this 100 guest wedding...
Is it rude, to ask my biological father, if he is still interested in being a part of the wedding and contributing as he originally promised?
I need some thoughts on this. It is a very trying and difficult subject for me. I have made huge efforts to be a part of my biological father/families lives, and I had to invite nearly 30 people from his family alone, and now I am concerned he has no desire to help with any of it.
