Disagreements

I have no idea what goes through her head at times. She has some hang ups that I can't solve. An example: there has been this issue lately with me disagreeing with her. When somebody offers up an idea to me, I always immediately evaluate what I see as its strengths and weaknesses out loud. Well, the lil mamma has been getting upset and she says I always disagree with her just because it was her idea, and she gets all frusterated. This happened yesterday, and it came out of the blue. We were just talking, like i would with anyone else, and all of the sudden it was like BLAM! "Sure, it's a bad idea just because I mentioned it!" and all of the sudden she is upset. I am not sure whether to blame this one on the raging emotions from her current events, or whether to think she really believes I maliciously put down her ideas. WTF? I am such a laid back guy, what the hell leads her to these types of things?

I think maybe I am just crazy. Maybe I am a shitty boyfriend and just don't realize it. I try really hard to do everything I can to let her know I love her while still maintaining some semblence of a life which is my own. She still sometimes says she feels like I don't treat her like I am in love. It's not all my choice. When she doesn't want to fish from dawn til dusk, I have to go with someone else. Should I feel guilty about this? I could never give up fishing, what's a salty dog to do?
