Better if we divorce ?

So, my husband and I have been together for 7 years and married for almost 2 years. We have never really encountered any hardships or a huge fight or argument. Nothing too crazy, but we do argue often but over silly petty things. To me it’s never a big deal. We makeup the same day and move on. But apparently my husband says it builds up on him and he’s frustrated and says I make him mad and I overreact. We don’t have financial problems or like I said any hardships. Last night again I wouldn’t say an argument because it wasn’t a big deal but last night when we got home from running errands I went to grab the mail and I seen our dog getting loose from her collar so I yelled at him (no upset or mad) to get her so she doesn’t get loose. At the same time I fell into the snow getting mail and dropped some of the mail. I went into the house and asking if he can help me and he said I overreacted about the dog and he began yelling at me. I completely wanted to avoid it all so I said don’t talk to me crazy and I’ll do it myself. Again, not mad or upset but avoiding whatever this can turn into. Nighttime comes and he is still mad and I told him that he needs to step by and let go of his pride and ego. I told him that our love should be bigger than these stupid arguments. He basically blames me for it all and I think it’s crazy because I never I see as who’s fault or who’s to blame at the end of the day I just always want us to makeup. I told him that I vowed to love him unconditionally and even tho we’ve never been through anything difficult I see the good in him through the good, the bad, and the ugly because my love for him is bigger than anything else. he then tells me he isn’t happy like he use to be and that we doesn’t know now if we’d have a long marriage all while I’m saying that we can work on things …. Should I leave him and we mutually divorce? I told him that I’d respect his decision because no one should ever be in a situation we’re they aren’t happy. I am also not going to pour all my love and fight for something when he doesn’t want this?

Thoughts, ideas, advice? What do I do when he’s questioning us staying married? And yes I’ve tried the whole communication thing and apparently I make him feel mad and upset.
