Sugar glider question :-I?

I got sugar glider half year ago, she is almost 2 years old now...Its very cute female glider, and she bonded to me in great way, I really have lot of fun with her.But no matter of that, still in the nights she got to bark sometimes even 5 times a night I would wake up and go to calm her down.So I decided to get another glider to be company to her.I got this little glider who is half year old, not baby, but still little.I had them in separate cages for 5 days, and then I let my female glider out of cage and jumping on other cage.But she gets ssso agressive to little glider and he is crabing very much!I dont know what to do...they 'seem not to like each other, what can I do to make them 'friends??Is it possible? I apreciate every help!
