<human>: Things havent been going smoothly with my girlfriend(35) and myself(25) and I feel like I want to break up... But i feel horrible doing so, especially with her 7 year old son being attached to me. 

 We've been dating for a year and a half now, and it started out stressful... But great.  Over the past 6 months or so theres been some big issues with compromise.  I feel she is a loving mother, but does not put the time or energy into her 7 year old son that she should.... She fails to discipline the way I do, or as intelligently as I do (reward system, consequences for poor decisions, structure) which I feel is imperative with her son with minor ADHD/defiant attitude.  I've also been polite as possible when it comes to working out, or taking care of her health(I can handle the age gap but if you dont take care of yourself, I dont feel its fair for your partner)  I've voiced many times what I wanted, starting politely but progressing into arguments fights etc.  I'd pay for equipment, membership, tried to get her to do it with me, but there is no enthusiasm or action.  Her parenting is inconsistent, which leads to a poorly organized household.  

Shes very sweet and loving, but ignorant and complacent to the things around her.  I wanted to evolve as  a couple, if someone puts in effort for me I'd always match it... But as much as i try to steer it shes set in her ways, she wants a future with me yet cant compromise even with my help along the way.

Not sure what to do here, love her very much but we fight at least once a week.  Might break up with her after the holidays? I can't bring myself to do it now....  Looking at what I've wrote makes this relationship seem unsalvagable, but I'd appreciate your thoughts and advice.  I've essentially turned into an impatient dickhead with my balance just not being met, and not feeling really good about myself.

Can you give me the gist of the text in a nutshell?
<bot>: Girlfriend wont compromise or adapt but wants a future with me, maybe I'm asking for too much and should just leave?
