<human>: So I've [m/22] been dating this girl [f/18] for 3 years we've had our ups and downs, but recently we went thorough some problems that she broke up with me because I was smoking cigarettes when I was at work without her so she was saying I was doing things behind her back yet when she would do the same I wouldn't say anything because I didn't think it was a big deal. 

Well when she broke up with me she hooked up with this dude she only talked to for a couple weeks, but she is the only girl I've ever had sex with and before this I was her only. 

After I found out about that I started talking to someone out of state but close to where my dad lives up north and we talked on kik and she started saying she really liked me and wanted for us to meet and I felt the same. I love the girl that I've been with but I just keep thinking about the other girl and what my girlfriend did with that guy. 

Right now we are back together, starting over to try to fix us but I'm do confused I don't know what to do. Any thoughts?

Can you summarize the given text in a few sentences?
<bot>: Been dating this girl for 3 years, she would get mad at me for things like smoking even though she was doing the same, but I didn't care
