<human>: We have been seeing each other since early January, and she left for work 3 days ago and will be gone for months, 8 to be exact.  

We have had numerous conversations about being together and putting a title on it, but some thing came up about 3 weeks ago where we were basically over with.  (Can go into detail if asked.)  

3 weeks ago, I did not talk to her for a week straight because of said incident which really hurt me.  She told me that during that week she has been contacting her ex boyfriend after putting him on the back burner to talk to me.  

We have since made up, and we talk frequently.  I just can not help but feel I am now on the back burner with our relationship/friendship and want to be the guy who is back on top.

She is not with her ex boyfriend by any means, but she said she was talking to him the whole week I was mad at her.  I can not fix this because I can't see her for a few months.

We have talked about me visiting one week and being with her for that week, but I can not help but feel I am now on the back burner for talking to her.  Maybe I am just self conscious about this whole thing.  Should i just ask her if I am now just an option?  or a second option?  I was once the first but ever since she said she was talking to her ex about 3 weeks ago is making me feel un-easy.

Any advice would be appreciated thanks

Give me the gist of the text in a nutshell
<bot>: Talked for months to a girl, had a fight, stopped talking for a week, talked to her ex for that week, feeling like i am on the back burner, do not know how to get out of it
