<human>: Can you give me a shortened version of the text?

Hi reddit,

This has been on my mind for a long time now. I need some help, otherwise I'll never be able to prosper more with my current girlfriend. 

Before I asked out my current girlfriend I was speaking to another girl at the same time, both for about 3 months. After that, I decided to ask out one of them (my current girlfriend). After that point the other girl always dawns on my mind and I always wonder what my life would be like if I had chosen her. I am happy with my current girl, but I always wonder if my life could be better.

I think my problem is that I want to confirm to myself that I asked out the right girl, But the only way I can do this is by meeting up with the other girl to just hang out and compare them both. 
The problem with that plan is that my current girlfriend knows that I used to talk to her and explicitly said not to have anything to do with her. Ever. I don't want to have to see this other girl behind my current girlfriends back. Because if she finds out then our relationship is probably done... But at the same time its killing me to know if I made the right decision or not.
<bot>: Talked to 2 girls at the same time, asked one of them out, not sure If I made the right decision, want confirmation. How do i go about this?
