My significant other makes me feel like a loser most of the time. iin?

My fiance is always trying to get me to be "more of a man" to "just do and not think or ask," and "pay more attention." Things along those lines. My problem is in how she gets these across, and it's usually in a fit of tears and frustration where everything that she has a problem with comes out all at once. She belittles me and when she's in one of her cry states suddenly I'm doing things that her bad parents used to do, or am acting like her father who she has a very poor relationship with.

I'm very patient with all this but some things kinda cross the line. An example was the other day we went to one of my sister's wedding and had a great time. We borrowed her mother's car and she drove. When we went to leave she had left the headlights on and the car wouldn't start. I went over some options, like AAA? or get someone inside to jump? Bump start? Things along that nature. Well she takes it poorly and starts talking about how I should be the man and get this figured out, gets frustrated with me when I go back inside and come back to see her pouting in the distance sitting alone. When I go to her she says it's my fault for not paying attention, I should have known what to do, I should have talked to my sober cousin, I should have found the jumper cables, I should have done all these things. Now she's pissed at me. We get it started and have a terrible and silent 30 minute drive home. At home the argument escalates and she starts going off about how I'm scared and scared of myself for becoming my father (who is dead and was an utter piece of shit) she says she understands because "she didn't have a father either" when in reality the dude is still alive and was actually there to raise her, unlike mine. So I got short and angry with her and it was strained until our roommate got home and we BS'd instead of relationship crap.

Next morning I get a text when she's at work saying she's sorry for being dramatic and she loves me and convinces me that I'm an awesome man and do all these great things for her... fucking blah blah blah is how I felt because of how she made me feel. I've been dealing with this for a while and when we go out she makes a scene like this all the time. This time it was my sister's wedding and she's so selfish she has to ruin that atmosphere too. I went from being the happiest I could be in my life to feeling like a sack of poop who can do nothing good.

Should I get out of this situation before we get married? Go to counseling? What the hell is wrong with her? What the hell is wrong with me?
