How our marriage will go if we go for it , I'm snake and she is sheep

We have been together for 3years but most times on distance , shared a flat together for first year before becoming a couple and had many arguments and good times too, however since we became a couple , we lived together only 3 months due to work, and it was ok.
Last 3 months We have been discussing marriage and sounds that many details we are not agreeing on and she is more expecting me to compromise..what is our chance do you think in marriage if happens ?
