So me and my gf have been fighting alot lately and the most recent was last night because i told my friend he could come to my house not realizing it was the same day as our 6 months and i told her i wasn't going to blow him off to hang out with her because it wouldn't be fair to him and she got even more pissed after that and we been fighting alot lately and not to sound stuck up but its mostly her, i have my flaws too but if something doesn't go her way you better count on us getting into a fight about it... and she said she is sorry and loves me and stuff and that she finally sees things but shes said that all before too and nothings different and i don't know what to do i mean i don't want to just throw it away but is it really worth me putting in all this effort if she is not going to put in any either? Ive tried talking to her about all of it before many times but it doesn't do much good after the first week and i don't want to live the rest of my life fighting with her over stupid things, and i really don't know what to do here any advice would really be appreciated. Thanks.
