<human>: Can you succinctly summarize the text in 1-3 sentences?

Okay, here goes.
 So lets start by saying recently i have not been the perfect boyfriend. My girlfriend lives a few towns away (2 hours) and i told her that i was at my house when in actual fact i was just chilling at my friends house enjoying a cheeky blunt after a week of work. She couldn't contact me (phone died) and asked my sister to see what was up, she then informed her i was not in. This happened twice because i'm an idiot you thinks it's easier to lie (she does not like me smoking weed but i have cut down).Shitstorm ensues and now feels like she can never trust me and wonders what else have i lied about. She knows i have been cheated on before and knows i would never do it but now she is having doubts.

Couple of weeks down the line we have a conversation about the value we hold to each other. Now she starts by saying you mean the most to me in the whole wide world, so i say 'what about your best friend' and she said more. Now i can't place people on a leader-board of worth to me, even if i would never tell them they don't mean the most it is still wrong to me. So i go on to discuss on how she is among the people in my life who i would do anything  for and mean the world to me (essentially my best friends of 22 years and my parents). But she evaluates this as meaning that she is not the most important and now feels like i don't love her as much as she loves me which isn't true and it saddens me and i cant make her understand. She thinks that maybe one day i'll love her more than them but it is just not in me, she is equal to them. I would give my life for anyone who means that much to me.

 She is a single child and doted on by her parents so it could be something to do with that. In her current living situation she is very lonely with a lot or university work to do so i just now feel awful for making her feel this way. I'm just really stuck and i don't know what to do.
<bot>: My girlfriend believes that if she inst the most important person in my life  then i don't love her with all my heart.
