I had simillar problems as well and I will share my ways of fixing it? One, if you are new and younger I have noticed the older/better pilots will not like you for a while. Flying two planes at once is common but also nerve racking. I started attending club meatings and socializing with the members I did get along with. I would bring up the NEED for a "newbie night" as some people made new guy's uncomfortable in the air. Expressing your idea of "fun at the field" with out bashing anyone will get your point acrossed and your goal acomplished. I have even had some of the guy's who did the same things you speak of try to make friends now and i still pay them no mind. I think this bothers there ego more!
