every day all day, on her break, before work, during work, after work. fuck the list keeps going. its not like i dont see her either i usually see her nearly everyday for a good hour at least. we usually go out for dinner and what not on weekends or friday nights. she wont stop bugging me. before you cast shame on me for being an asshole please take into consideration the fact that i do infact love her but i need my own time sometimes. i grew up as an only child with a single parent where as she grew up in a huge family so i am used to being alone and can cope well with it and even enjoy it sometimes. how can i make her understand this without making it seem like im a fuckhead rude asshole?

tl:dr how can i let my gf know i need some of my own space without sounding like an asshole?
