<human>: Give me the gist of the text in a nutshell

Hi, got little problem and i will try to explain everything in short story.

My girlfriend is one of these girls that dont do make up everyday, and for sure never in the evening for me. One vening she had her friend plumber coming round to fix her shower, when i turned up at hers that evening she was wearing full make up looking all nice.
For obvious reasons i didnt like it, but ok i understand its a women in the end and she likes to impress others, its just wasnt nice as she havent done it for me in months.

Another thing that happened same day, she bought new side unit that came flat packed, i wanted to put it up for her and even took the pieces to start it, but she told me to leave it as she want to do things by herself with no help just to see if she can, i respected that and i left it so she can do it.
Later that day when i turned up i found that she asked this plumber friend to do it for her, which made me feel worthless and made me look like asshole in eyes of this plumber.

In the end when i confronted my girlfriend about all this she just got angry at me, and told me its over between us.
<bot>: dont understand my girlfriend behaviour and reason to break up. Should i try to talk to her and apologize ? is it my fault ?
