Hey guys I just want to know whether I overstepped my boundary a bit. 

Me and my gf(both mid 20'sF ) have been dating for 3 years. Recently she got a makeover as a surprise to me for our anniversary. She always knew that I had a thing for septum rings.

So she gets her septum pierced and cut off all her hair. Honestly I don't know what she wanted but she ended up getting a bowl cut which looks funny on her and her septum wasn't impressive either. 

I didn't respond and told her she looked good. At night she initiates sex and I'm not too excited. She keeps pestering me and asking me if it was her makeover and I eventually replied yes. I told her that it looks like a bowl cut and her septum doesn't look good either. She broke down crying telling me that she did all this for me( I never insisted on anything FYI) and she's disappointed that I didn't appreciate it. 

I feel like shit but AITA?
