Thanks guys. I put in my word today.
I am waving my dwell time and trying to go back, it is what I do, who I am and it is my duty. Marine, do not worry about what others think, it is what you think is the important thing. In the end, no matter what you decide to do, this Vet salutes you 

This will be the third deployment I've opted for, but I got passed up on the other two because they needed NCO's (I'm a Lance Corporal)m but now they're short on everything, especially E-3's.
Marine...sounds like you're a pfc...not an easy pay grade to try and support a family...regardless of your mos, all marines are grunts first...if your fiance is the only thing holding you back, put her down as beneficiary on your life insurance and make sure she has access to your bank account...set things up as if she was your wife...would be better/easier if you were married but...
going over there is going to be a life changing experience...especially if you see action...you may not be the same person when you get back...be sure she understands that and can handle it...be sure you can handle it.
the decision is solely yours to make...it's rare to be given a choice during war time...in my time we volunteered before they asked but this generation is different...whatever you decide, it has to be you and you alone to make the decision.

Past due for Cpl - but the USMC has pretty much frozen promotions(funding).
She knows I can change, her family was military to the max. She's told me that no matter what happens that she'll be right here beside me.
As for being able to volunteer, it's because they're in short supply on a large scale.

If you're going to marry her anyhow, consider going to a justice of the peace and get a quickie marriage done. Get her enrolled on base, registered as a dependent, etc. Get a living trust through the base legal office.
Have a regular wedding when you get back.
I'm thinking that's what we're going to end up doing. Never really been briefed on the whole marriage ordeal for the military but I'll go up my CoC and see what to do.
Do as your heart tells you. Just keep your wits about you and remember that you are mortal and simply just can "re-up from the SW runway" is you get shot down. 
Best of luck!

What do I do if they get a CAP then? Can't I just up a death star and roll at 'em over and over??

Thanks for the support again guys.
