How should I deal with this situation?

What should I do? About a month ago I lived in a shared flat with 5 other residents. About a month ago I moved to a "girlfriend" in her apartment. Everything has always worked out. But for about 2 days she is very different. She has an ex-boyfriend who is extremely weird (brutal, drug addict, cheeky). He is always stressful and she can't handle it. What I can understand. But she always runs back to him and provokes him extra. In the end, she is beaten by the ex and she is crying out to me. It's not like I'm never there for her. But on the contrary. I'm really the last person to say I'm fed up with their howling. But I realize myself that it makes me ready. If she has a problem, then she arrives. But when I have a question or want to say something to her, she ignores me and pretends she does not hear me. And that's what makes me really aggressive. If she wants something, I'll give it to her too. But just not that I want to have something or want to know something. That does not work then. She always wanted to watch Netflix and I made it happen to her. I got my Sky Receiver, she did not like that, then I bought a Ps4 a few days ago, because then she can Netflixen and then I can also abreagieren through ps4 play. I'm also the only one who keeps the budget in shape. I sweep, wipe, vacuum, do the dishes, go shopping, do the laundry, hang up the laundry and and and. But you? She walks with her dog and howls around… It gets to my head that she does not do anything but ignore me or get me out of her bad mood. It's really slow. Actually, we like each other and get along really well. She said recently, we would be the hottest WG.

What should I do? I've talked to her about it a couple of times, but she ignores me or she complains.

Honestly this is just my opinion that sounds like you are her little servant for everything if she really ignores you intentionally but always wants everything I would say once confronted with the opinion of the best if she can't get away or change the room and if they only rummault and no understanding shows nothing out there because it is not bad if you are there for someone but if it makes you already done you have to draw a line and it would be a pity if you break it

I'm going to break it for days. That also explains my bad mood. For example, She also looks at men with whom she has something as a toy. No more and I had something with her. Or that I should always keep my mouth shut when she goes shopping. Yes, I'll shut up. But still
