My girlfriend of 6 years told me two days ago that she wants to go on a break because of us fighting all the time. She took all of her stuff out of my house and left. I don't know where she is. She also gave me this nonchalant hug before she left too. I called her last night to get some closure on the situation. She told me she has not been happy for a while because I have been a very negative person for a while now. (Which I have) She was definitely putting more in than I was and I wish I could have changed myself sooner now. She said that she wants to be her own person for a while and see whether she is happier with me or without me around. I asked her if she wanted to break it off forever and she just said " I just need to think" I also asked her if there was another guy and she said no. I told her that I am sorry for the way that I have acted and I respected her decision. I told her to call me if she needs anyone to talk to and I wouldn't push our relationship on her while talking. What should I do? I don't want to lose her. I Love Her so much.

This sounds all too familiar. She broke up with you dude. Have some self respect and go stop contacting her and move on with your life. Don't be her friend or anything because that will pro long the hurt. Tell her only to contact you if she wants to get back together or don't even contact you at all. By that time, you would have moved on with your life and you can decide to take her back or not. The most probable outcome is, you don't want her back anymore because by that time, you would have made something more out of your life that you couldn't when you were with her.

I agree just give her space you don't want her to feel anymore smothered by you then she already is that will make things worse find something to do during this break to get your mind off things send her flowers to show you care but DON'T go over board by the way answer mine https://www.askmehelpdesk.com/go/index.php?home

I agree give her space and time. If there's a lot of fighting and you are negative a lot and receiving more than you are giving then yes she needs a break and while she is on that break you need to work on yourself. It's not fun being in a one sided relationship. It gets lonely.

Be patient and if it's meant to be she will come back. Respect her "need" for a break. If she decides to move on then learn from this :)

I hope I help some.

You have to assume and go on, as if she is not coming back. This is almost always over. Before she goes is when you needed to have talked, went to counseling and got help to fix.
Normally now, it seldom works back.
