Reading your post reminded me a lot of my ex that I broke up with just over a month ago. He had anger issues that really affected my mood negatively, even though he wasn't being abusive in any way. It was one of the major reasons I broke it off. We were together almost 3 years and that gave him a lot of time to change but he ultimately didn't work hard enough at changing.

If he is willing to do the work to overcome his anger issues, then I'd suggest giving him another chance. If not, you'll need to evaluate the pros and cons of this relationship and decide if it's worth staying in. I wish you all the best.
