I've been trying to write Remus/Tonks for quite awhile now, but I find my interpretation of their relationship to be tainted by the classical music scene. We see relationships between women in their early twenties and professor types in their late thirties/early forties A LOT.

At some point, male classical music soloists get into what I call THE ZONE. Early thirties/late forties. Profile:
1) He is married to long-suffering women their own age. His wife is also a musician, and the two of them met in university. Optional: They have one or two children, and the wife has put her own music career on hold to look after said children while hubby goes on tour.
2) He goes on tour, bringing him to many summer music festivals, where he is in contact with adoring music students, or gives masterclasses to adoring music students, semi-successful concerts which are attended only by music students, etc.
3) He is hot (young) enough still to be considered highly attractive by the female music students (all in their early twenties), who throw themselves at him in droves at said masterclasses, music festivals, etc.
4) He drinks. A lot. Goes drinking every night while on tour with said music students. They laugh at all his jokes and think he's awesome. He wants them to think it, but feels a bit guilty, knowing he's really not.
5) He has done this before. The whole... relationship thing. Even if he is not particularly cool, he has learned some moves with practice. This is good enough for adoring music student groupies.
6) He is, actually, a great guy, a good musician, and a good teacher.
7) He does, actually, fall in love. Or thinks he does. A lot. He doesn't mean to use these young girls, but ends up doing so anyway.

Ect. I haven't written about this very well. I know Remus/Tonks isn't like this... but there are some elements of R/T that DO fit the relationship pattern that inevitably happens. Let's say that R/T is a coffee with a tiny flavour shot of this type of relationship. Things that remind me of it:
1) How Remus/Tonks is kept pretty quiet, and it seems to come out of nowhere. These relationships stay secret until they don't.
2) Tonks seems to be a really cool girl who suddenly falls terrifyingly in love. It throws her completely off balance, and she loses some of herself. Suddenly, she can't morph anymore. Suddenly, her Patronus is all about Remus. Is it love? Or is there a tiny bit of... obsession in there? You decide.
3) Remus is ultimately insecure and is convinced Tonks is better off without him. The age difference bothers him but not her. It means nothing to her. This will always happen. It's so easy to be the younger one and not care.
4) Remus is a fantastic guy. I fell in love with him in PoA. (Uh-oh. I was, like, how old at the time? You see it working, even though a novel?) But he is kind of a jerk to Tonks. This always happens, too.

Anyway, it's late and I'm not getting this out very well. But essentially, my Remus/Tonks fics always have Remus come out as a bigger jerk than I think he is. I LOVE Remus, and I just can't make him that jerky. But I think he might have been that jerky anyway.

I've seen it happen SO many times, guys, and I'm only 23. Tonks has personally cried on my shoulder. Okay, it wasn't Tonks. But it could have been.

I've so far managed to avoid this sort of relationship, though if I had done it, it would have happened with... well, I can't tell you. But, of course, I did meet Tom (my boyfriend) in university, and he's also a musician, and will be a more successful violinist than me. Will he leave me for a student with I'm 40? Probably. I should get a pre-nup.
