To clear things up a bit, I have definitely become uncomfortable with diving with this individual. I have stopped diving with him & until he can accept my limitations & I will not dive with him again until that time. His attitude during a dive was, "OK, if you don't want to do what I want to do, then I'll just do it by myself". I am not one to normally abandon my buddy, but neither will I risk my safety or life. I guess my delima comes from the fact that I did my rescue class with him as my buddy & we became decent friends. I worry about him & his ambitions blinding him to the dangers of what he's doing. I do think that there are some divers that can self train, & I'm not against it. What worried me was this individual would take the information he wanted & ignore the rest (basically he would read or hear what he wanted & disregard what he didn't want to read or hear). From what I'm reading, I should basically accept the fact that he's not going to change his mind about what he's doing & go on. I guess, for me it is just the concern of a friend. However, I just found out from another source the other day, that he finally did decide to obtain training for what he wants to pursue. That is a great relief to me. Some others that I dive with (& who have dove with him also & were also worried about the path he was taking) talked a Technical diving instructor into discussing the potential dangers of what he was doing. I give the instructor kudos for tactfully explaining why some of the things he was attempting, in the manner he was going about it, was not good. Hopefully this training will help him grow into a safer & better diver. I thank you all for your thoughts & suggestions.
