I am only a beginner with Irish. I have been studying for about two years but I don't consider myself conversational. I want to start learning another language in conjunction with Irish but I don't want to be confused. Does anyone think this is a good idea or should I wait until I have a better grasp on Irish. If it helps the other language I want to learn is Spanish. My girlfriend is half-Chilean so most of her family speaks it and also living in the US it is a lot more accessible than Irish. I feel the two languages are pretty far apart that it wouldn't be that confusing as opposed to if I wanted to learn Scottish Gaelic or something but I wanted to hear more opinions before I started.

Go for the Spanish. I have spoken it for years and it's about 10X easier than Irish for many reasons (chief of which is that you are surrounded by millions of people who speak it fluently and don't mind all sorts of screw ups and imperfections). It's a great 2nd language and I find that sometimes it's easier to figure out some things about irish coming from the Spanish side.

I'm doing both Irish and Spanish at the moment.

It's a bit different for me, as I've been learning Irish for 60-odd years, so what I know is fairly close to the tip of my tongue - my reading and understanding are fairly fluent (it's just that pesky spelling, grammar, and speech-block!!).

What works best for me is to do them on different days - My Irish Class is Tuesday, and my Irish conversation group Wednesday, so I turn on the radio RnaG early Tuesday morn, and do no Spanish until Wednesday evening.
I sometimes need to do some Irish before the following Tuesday, and that does impinge a little on the Spanish.

When I was studying Spanish and German in back to back classes I would do things like pause in German speech with a long y (Spanish "and"), and other little mix-ups. I think dividing the time is good, and since it is pretty rare that you're going to meet a speaker who is fluent at Spanish and Irish, I imagine that you'll keep the two languages in their camps. What might be good before lessons/classes is to have a small warm-up before you start class so that you'll be in the mode and your time there will not be wasted. Good luck.
