<human>: Lately I have been thinking about breaking up with my GF.

We only see each other about once a week and maybe have sex once a month. I always have to initiate it and it always seems to be a chore for her.

The reason we see barely see each other is because I am currently working 2 jobs and am going for my professional designation whereas she is studying nursing. Our schedules are completely opposite.

Our view on finances is completely different, I am very frugal whereas she is always talking about what next to buy in terms of material items. 

She wants to have kids in the future and I have told her multiple times throughout the years that I do not want any kids whatsoever.
I honestly can't see myself marrying her due to all the little differences we have.

Lately it has gotten boring, she left for a month and half earlier on in the year. I don't think I actually missed her in the time frame she was gone..it felt liberating to know that someone wasn't watching over my shoulder.

We don't really have too much alike, I am into cars, investing, health & fitness whereas she is mostly into shopping, tv shows, etc. All of the things I am interested in I can never hold a conversation with her about.

The main problem is I don't know how I am going to do it. She is a wonderful person that has been completely faithful to me and I think I may just be selfish in how I am thinking about our relationship.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Long term HS gf, barely see each other, complete opposites, not sure how to break up or if I should or if it is just a temporary thing that I am feeling this way.
