<human>: Can you give me the gist of the text in a nutshell?

Be sure to explain in detail with line breaks.
my girlfriend of 3 years has just said she needs time to think of whether she wants to continue our relationship. We have had an amazing 3 years, travelling together and had some amazing times. she used to be quiet depressed and self concious, whereas I was always very happy. I loved her so much but lately I've felt a bit down and have been more needy towards her whereas she has become happier and more social

I feel like because she is happier she feels she doesnt need me anymore. At the same time I've no idea what she's gonna say in a week even though last time we talked she seemed quiet sure we were breaking up. 

During this break I've realised that we were never that in touch emotionally, she wouldn't want to talk about anything serious or painful. I'm thinking of just agreeing to breaking up or insisting on it if she decides not to. 

She's such an amazing person and I don't want to let her go. We worked so well almost all the time. If we do end up back together though i know we would need to connect more emotionally but I'm unsure if this will ever change and unsure whether it'll be worth one more shot. I've tried incredibly hard to help the relationship but I don't feel shes done the same. Do you think this could ever change?
<bot>: Mandatory summary/question! We're on a break which she initiated. If she wants to continue the realtionship, should I accept or decide to end it myself?
