First of all, I don't agree so much with the fact that the chronology is difficult to follow. After all The Room seems to be pretty linear in the way the story unfolds. Disregarding the slight unconnectedness of some individual incidents, if the movie doesn't suggest otherwise, I have no reason to believe the chronology to be non-linear in any way. Thus my chronology of the events would be the same as presented in the movie (even if that might not be ragarded as "reliable").

I agree though, that I also couldn't completely bring this tuxedo scene in relation to the rest of the narration. But it also seems quite impossible that this could in any way happen after the birthday party, as that is when everything collides, especially Johnny's relationships with Mark and Lisa. Additionally, it is clear that he was not married to Lisa during the birthday party (and thus before his death), since at this party he still calls her his "future wife". Thus from the movie itself I can only conclude with a very definite

No, Johnny didn't get married to Lisa.

But in contrast to Meat Trademark's answer I wouldn't attribute anyone using the word "wife" to be just a mistake or a plot oversight. Rather than that they were just using the term "wife" colloquially, in anticipation of Lisa being Johnny's wife in the near future anyway. This is similar to Lisa's mother calling Johnny her (Lisa's) "husband" earlier, only to be corrected by Lisa. This inaccurate use of the terms "wife" and "husband" adds to the fact that apart from Lisa everybody else seems to see her marriage as more or less predetermined and that Lisa's unwillingness to accept that and her anticipation of the boredom of being a "wife" is in fact the major motivation for her devastating actions. In addition to that Mark might also have said "wife" to make the explanation easier and not disclose everything to Peter.

First of all, I don't agree so much with the fact that the chronology is difficult to follow at all. To me The Room doesn't have a very complex story or narrative and seems to be pretty linear in the way the story unfolds. Thus my chronology of the events would be the same as presented in the movie (even if that might not be ragarded as "reliable").

I agree though, that the only incident I couldn't completely bring in relation to the rest of the narration was this scene in the tuxedos. But it also seems quite impossible that this could in any way happen after the birthday party, as that is when everything collides, especially Johnny's relationships with Mark and Lisa. Additionally, he was not married to Lisa during the birthday party (and thus before his death), since at this party he still calls her his "future wife". Thus I can only conclude with a very definite No, he didn't get married to Lisa.

  In addition to that he might also have said "wife" to make the explanation easier and not disclose everything to Peter (instead of saying "I have an affair with a girl named L. that is going to marry a guy named J. next month, wait scratch the last part, I didn't say that").
