Relationship Issue (Should I break it up or not?)

I haven't been happy about him for a few months, we're constantly arguing, and it doesn't feel the same anymore. I don't think we love each other enough to stay in a relationship. I feel like he's always hiding stuff from me and making me look stupid in front of everyone that knows us. Should I break up or try to work it iu? Keeping in mind I've been trying to fix us up for about 5 months. We have about 3 happy moments out of 10.
