Long story short(ish): I'm a man in my late 20s who's been in a relationship for the last two years. The last months, I've been struggeling with the idea of this being my future... I work full time in a quite well-paid job while she has a low-end part time job. I pay for housing and our two cars plus most of our food. The GF had two kids from a previous relationship, kids I love as if they were my own. However.. The oldest kid has an illness that requires around the clock surveillance, as it is potencially life-threatening. This job has fallen on me during night time, as she doesn't wake up from the alarms. This often leads to nights with several wakenings and a tired self the following day.

This I can accept to some degree, though I'd be very happy for being able to sleep a whole night once in a while... One would think the gf would step up, especially those nights she has the following day off. That has never happened. As such, I have a quite stressfull and demanding job, but lack the option to get fully rested.

What really grinds my gears though, is the lack of respect I get from my gf. Me doing something for myself (meeting family or friends alone etc) is often met with frustration and some times even the question why. Last night we even got into an argument over me "hogging the newest car constantly". The car I've bought. The most reliable car we own - I deliver the kids at school. I often take the nr 2 vehicle even though I feel somewhat shamefull compared to my coworkers and for those who pay for my advice. (Most of my coworkers have porches and high end cars, my clients the same). My GF needs to "get some status, thus the fancy car". She's a freelance nurse with no steady work schedule, more often then not the car sits at home or at her friends house then anywhere else while I'm at work.

I feel that as a lack of respect. I've given up on several hobbies for the family, I rarely see my old friends anymore and I get frustrated over that and the fact that I have to pull the weight at home as well.. My gf is often "ill, and uses that to get me cooking dinner for the kids, laundry etc.

I love the kids and the woman, but my patience is stretched far. So.. how frustrated is "normal" in a relationship, and when is moving on a legit option?
