What am I supposed to do?

Me and ex are trying to fix things. I'm so tired of fighting with him. But it seems nothing ever gets accomplished. So I tell him I'm upset, I tell him why, I tell him how to fix it. Not in a bossy way, but he asks what's wrong, so I tell him and therefor..fix that, I'm not longer upset. Bam problem solved. But it never happens that way. In a sense I completely feel like I'm putting way more into the relationship than he is. But either way, I still have things that are bothering me. More fighting could mean the end of us, which I really really don't want - although I'm not seeing a light on the other side of this tunnel right now but still - I do still have stuff that's bothering me though. Should I bring it up and take the risk of one more fight being our last, or just try to drop it forget about it and hope all goes well?
