The fact that you're able to point out that the fights are small but this makes you actually question whether you should try to fix things speaks volumes more than the line where you say you "love her a lot" Don't take this the wrong way but if you plan to get married you need to be at a point where your level of commitment is to always fix it and make thing right and not so quickly move to the idea of getting out and moving on. Commitment itself is part of showing your love for your partner.
