You know, I used to have a similar belief, but that's because I was uninformed about the flaws in evolution. I'm not saying that you are uninformed, but it's definitely something worth exploring further. Even after 150 years, there's a reason why it's still called the "Theory of Evolution," and not "The Law of Evolution." When I realized that I could trust what the Bible said about creation, it was a very liberating thing.
Anyway, I don't know whether or not it's "wrong" to believe in both God and evolution, but I will say that once you see the flaws too, you will draw closer to God because what He said was true all along, proving His faithfulness. :)
