Advice Concerning Mentor/Angel Investor (I will not promote)

Currently own an Algo trading company. I was connected via someone within my family who has a college friend that is an MD at a very well renowned bank (BB). I had dinner with this gentleman and pitched my company and project to him that day. within a week, we had planned a time to give a pitch. 2 weeks pass and on the day of presenting the pitch deck, my co-owner was severally sick and couldn't make it on the call. Shit happens. Anyways, deck meeting goes really well and MD says he is going to send the idea to two angel investors, one in cali, and the other the ex-CEO of this very well renowned bank (MD is currently doing a venture with him). Now obviously, MD says that he needs to talk with co-owner first before sending email to the two angels. Understandable. My co-owner contacts MD, no answer. I text MD trying to clarify, he says he will contact him on a specific day, he never contacts him. I text MD again saying something along the lines of "whats going on with this? haven't heard back is there an update?" he says "busy unfortunately, i'll reach out when I have time". It has now been almost a whole month since MD and I had our meeting and still nothing has happened with him contacting my co-owner. I have a constant sense of urgency with this, especially considering the fact that I want to receive funding by the beginning of Q2. I also do not know how to express this frustration and constant postponing to MD without sounding like an asshole. Now one bit of good news, the MD is currently living in Miami. I will be there in around 3-4 weeks time for an event which opens up the possibility of me talking with him there. However, I initially wanted my arrival at Miami to initiate a meeting with one of the angels, not to clarify a lack of communication between MD and I. I am 19 years old and still in school so apologies for a very ramble-heavy rant but I would appreciate some wisdom, guidance, and/or advice on what to do in my current position. thanks.
