Need some advice

My boyfriend is in the National Guard Army and is getting deployed in 4 months to Afghanistan. We haven't been together super long, four months to be exact but I know he's the one I want to spend my life with. We've talked about marriage before he leaves and at first I wanted to wait until after he gets back which is a year long deployment but now I'm thinking other wise. I love him so much and if I know he's the one why not get married before and have a bigger wedding later on. I've gotten a lot of support from friends and family saying they don't see anything wrong with it so I figured I'd get a little more input on it! 😊
