The two of you are as mismatched as odd socks, but it's not all bad news. You probably came together in some type of dramatic circumstances, and the hangover from the tumultuous meeting is causing a sort of emotional hangover. It could be that one of you still has one foot in other relationship -- have you got the roaming eye?
Or is it your partner? Regardless, suspicions and mistrust have cast a pall on your pairing. The sweetness has drained from your dealings; you view each other as enemies to be conquered. Where's that 'you and me against the world, honey' spirit you once had?Your rough spot is not an easy hurdle to simply hop over. Most of the work here has to be done by you. You need to be clear on what you want. Who do you want to be with? Where do you see yourself in five years? Where are you going and why? Acting on emotion alone will only land you in tricky situations; you must act in your best interest and weather the uncomfortable emotions the transition brings on. No one ever said the path of true love runs smoothly; an adult doesn't expect it to be that easy.
