Is there still hope?

I’ve been with my boyfriend for a year and for most of it we have been arguing about the same thing. He wasn’t sure if he loved me and in turn I would get upset wondering what I was doing wrong and impatient thinking that he would never love me back and kept wondering if he was worth waiting for.

He recently has told me that he knows for sure that he loves me, which is great! However I do feel terrible for how I have treated him in response to the situation. I have been horrible, blamed him for making me feel so depressed all the time for not knowing how he felt. I would make a big deal out of the tiniest issues, and left him always worried that I might suddenly have a go at him. It just wasn’t great not knowing how he felt about me and getting disappointed everyday when the day would pass and he still wouldn’t know.

I want to change and become a better person for him, I love him and I want him to be happy and I feel so terrible for how I’ve been.

Does anyone have any advice on how I can handle my temper better? I’m hoping it will be much better anyways now that I know how he feels about me. And is there still hope for us after everything we’ve been through? I was thinking that we can put all this behind us and use it to make our relationship stronger.
