Confused and not knowing what to do

I don't really know where to start. My wife and I have been together for about 7 years. We both married younger then we wanted to but consider the situation we had no choose but to get married I was 18 she was 17. We have been through a lot over the years mostly about our kids and the all hours I worked. We worked through them and we pretty much straight on all aspects of your lives well were. The reason for posting is because I'm very confused on what do. My wife cheated on me I found out and decide to move in with my brother (we are very close he also my business partner). My wife and I have been separated since march that when I found out about her cheating with one of her class mates. My wife decided to go back to school when our kid stated going to school. The problem comes in with my wife wanting to come back home. I on the other hand would like to go back but I kind of like the single life and I am not so sure am ready to commit to her again. The only reason I am even considering going back is for my kids. I'm looking for advice for someone who has been through something similar and who could give me some advice
