Relationship with boyfriend or the army??

My heart is hurting so bad. I can't stop crying. My boyfriend was just about to propose to me within a few weeks but I just got a call from him saying that he is going to be deployed in January for at least a year. He is at training right now and we are currently apart from each other. I cried for a week before he left for officer training. And now I just found out he's deploying and I feel like someone ripped my heart out of my chest :(   We made so many plans. We were looking at apartments, and I already picked out my ring and we were planning our wedding for next summer. But none of that can happen now. I mean I knew he would eventually have to deploy but I thought we would at least get a year together. My mom was kicking me out of the house in December but me and my boyfriend already had our plans and now they're ruined! Now I have to find somewhere to live for the time being and find a job and everything. I don't know how to get through this. I'm scared our relationship isn't going to work. He always talks about how he sees soldiers cheating overseas. I'm so upset. This morning I had no idea I would be shriveled up in my bed pouring my eyes out. Has anyone else had to deal with a deployment of a loved one? Does the sadness ever go away
