AITAH for taking a day out with friends to rejuvenate

I am in a live in with my girlfriend of 2.5 years. We have been in live in for nearly 6-7 months now. Recently at my office the work load increased exponentially, so much so that i didn't even get to celebrate NYE and i have been working over the last two weekends as well. My girlfriend also has been very patient and didn't celebrate NYE for two reasons, first i had work and second she doesn't have that many close friends except me.

However i did take her out whenever i could even for a couple of hours last weekend. And we spent the whole day yesterday watching a webseries.

Late at night though we had some heated argument which started with her smoking habits and health. After some time some of my friends called me over since i didn't meet anyone even on NYE party. I decided to go and i even asked my girlfriend to accompany me. But she was still mad and started crying saying I don't spend "quality time" with her. Now we have had this discussion in the past as well and i am actually tired of having this discussion about quality time. Because for me i spent the entire day with her, i live with her and if that's still not enough I don't know what will be.

Anyway i left to meet my friends cause i seriously wanted to unwind and when i returned home at 3 AM she was awake and started talking about leaving the live in situation and look for her own apartment since according to her the live in thing is not working.. so am i the AH?
