Narrative:

The captain and I talked (at length) about many things coming into dal and he pointed out that we aren't supposed to fly to 13L after (time local). So I had it ingrained in my mind that we were landing on runway 13R. After being given very unusual vectors for a right downwind; tower asked if we wanted 13L or right. The captain said 13L would work better for us. We set everything up accordingly. This captain and I have flown together before and he is very vocal and full of all kinds of 'helpful hints' and other superfluous information. I was fairly fatigued from the late start of this trip; coupled with a restless night of sleep the night before. I told the captain that I had the runway in sight and I locked onto 13R. As I positioned the aircraft to line up for a visual (still way out on final) dal tower called and asked us if we wanted the right since it appeared we were lining up on it. The captain replied 'no; we will take the left.' I couldn't believe I had lined up on the wrong side since I had never done that before in my aviating career. We started side-stepping and I felt like we were getting ourselves set up for an unstable approach and we elected to go-around. After going around; tower then cleared us for the visual to runway 13R. I was beating myself up after the lining up on the wrong runway stunt and I was getting even more 'helpful hints' thrown my way. As we were on a base; the tower called out company traffic on final to us and I told the captain I had the runway and the traffic. I was still feeling distracted and quite frankly discombobulated and darned if I didn't turn and roll out to line up for runway 13L. The captain noticed (as well as tower) and we made the turn to line up and land on runway 13R. I actually gave the aircraft to the captain because I was disoriented and very aggravated at myself. The rest of the approach and landing were uneventful and tower didn't mention anything regarding the two approaches. I take full responsibility for my actions. The cockpit was very dynamic for both of the approaches; but still no excuse for either approach.

Title: B737 flight crew describes a night visual approach that becomes unstabilized when the First Officer lines up with the wrong runway and results in a go around. On the second approach; the First Officer again lines up on the wrong runway and the Captain takes control for landing.
