I told my DP a few weeks ago that I want to split up as I've been unhappy for quite a long time (bar some better spells in between) and he is being incredibly nice and making an effort. The reason I want to leave is that we don't communicate well at all, he has anger issues which result in road rage, punching walls etc, I feel he doesn't appreciate me and I just don't want to live my life this way. I love him but I know the relationship is toxic and I don't see how he is ever going to change long term. He's asked for another chance for a few months and if I still feel the same then at least we tried everything. But part of me thinks that he will be nice as pie for the next few months then eventually we will be back in the same toxic cycle. How can I be strong? Or should I give him another chance? I just don't want to look back in a year or 2 and be so unhappy again. It's taken me so much to finally tell him I seriously wanted to leave and I'm worried if I give him more time of us both trying that I'll lose my resolve and not leave even if I'm still miserable. But I love him and he's making it really hard to stick to my guns. Thanks for any advice.
