Input: Hey guys, gals &amp; all in between. My GF and I have been going out for 3 years, its been great for the most part dotted with the usual few tiffles every couple experiences once in a while.
The other night I was out in the company of an older couple who I know (I'm in my was, they their 50s), but she didn't yet. They wanted to meet her and so I offered her the invitation for when she had finished work. 
She arrived down an hour or two later on with her friend and we all got talking, but she was being a little overpowering to say the least.She is quite a theatrical person in ways, and has been told on occasion that her voice is too loud.  I caught her a couple of times interrupting my older male friend mid-sentence to launch into what she had to say and I noticed his (mild, subdued) annoyance, compared to how he had been with me earlier on. 
Anyways the night goes on and we say our goodbyes, they tell her what a lovely girl she was and it was a pleasure to meet her.
As we are walking home together I try to bring up that I believed it was rude to talk over people and that she had been a bit domineering in the conversation. I must stress that I tried to approach it tentitavely as she has a tendency to take things to heart very easily. She flipped out, the argument persisted all the way home and she ended up sleeping on the couch. 
She is still not over what I said (this was about 4 days ago) and I have apologized for hurting her feelings &amp; bought her roses ,but she claims that I am shattering her self-confidence and that she doesn't feel she knows how to speak around people now.

I admit that this is not the first time i have let her know how i feel when i believe she is wrong.
Im of the opinion that one of the most important things about relationships is that since you inevitably spend the most time with your other half you both have a duty to keep eachother in line and on the road to self-improvement. She feels that I am being too hard on her and "she will never be good enough so we might as well call it quits". Its tough to talk her out of these situations because when she is emotional i try to stay calm &amp; speak logically, in an attempt to bring her back down to my level, but she sees it as me being condescending.
She made a reasonable point that "everyone" talks over eachother, and tbh I have caught myself doing it out of excitement before but I immediately notice myself, she seems completely unaware of herself at times.

AITA?

telling my gf that she can be too dominating in social situations
