<human>: Our relationship has always been a roller coaster, which has more downs than ups. Two or three friends have already asked me why did I keep this relationship and I myself quite dont know the answer, sometimes seems like Im just pushing it foward and hoping that it gets better.

But as I said, It has some up points, which are somekind rare, that makes me think that we are doing ok. Plus, Ive ended my last relationship because of this exactly same reason and I regret it every day (Been 4 years since that)

And because of that, Im afraid to break up with her. Im afraid to miss her and Im afraid to regret again and have to go throught all over again.

Provide a brief overview of the text.
<bot>: Relationship like a rollercoaster, friends telling that my relationship sucks and shes not of my kind. But I dont have the balls to end it 'cus I regret breaking up with my ex.
