I'm stucked with a position where I felt blame all the time I see something wrong in my relationship. I know this is wrong but this is killing me.

Some points I dislike:

1 - She doesnt have much money, so I have to pay for most everything. She is not the kind that want to go to expensive places of parties... but even doing the basics it's still expensive and a bit frustrating. I ask her to help me, she say she wants but sometimes it's like she doesn't care so much.

1.1 - A time when she wanted to go to a wedding, she give a way to "find money" to pay for her R$300,00 dress and I got mad with that. Why she find money for something like that and can't find a way to help our relationship costs?

2 - Sometimes when I want to be alone or no date on days like (Friday, Saturday and Monday) even if I say I had no money, she got angry and try to make me feel guilty.

3 - She seek for attention... We had a lot of fight because I didn't answered her on whatsapp, only because I was focused working or doing my stuffs... and even after a long time discussing she still sometimes throw that on me.

In some aspects I like her, we have some good moments and I can feel that I have feelings for her.

But, am I to blind to do not accept the weight it's getting on my back? It's like I'm carrying everything and she doesn't recognize that when we have fights.

I spent R$1000,00 (Brazilian currency) every month with this relationship... and I'm not married. And when I want to do something alone, she freak out with me.

>>UPDATE: Just being clear, I don't want relationship advice or how can I solve it and stay with her. I need some help to open my eyes and get out of this situation. I know its wrong and I have to stop doing that to myself. If this is not the place for that, ok... I wont ask for it here.
