Power School

So I went to go visit my fiance about 2 weeks ago when I was on spring break, and that whole time together was just amazing and perfect. It was just so great. It was an unexpected trip that was pulled together in about 2 weeks, but it worked out great because he got liberty for 4 days and it was right before Power School and I was on my spring break. We had to say goodbye, and at the last minute he told me he was unable to come home in September like we planned after Power School because he couldn't afford that and to come home in December with the wedding. So now instead of 6 months I have to wait 9 months to see him. Which made saying goodbye about a thousand times worse because I know that would be the last time we saw each other in almost a year. Then to top that off I got stranded in Atlanta's airport for about a day due to late flights and missed connections. And normally I get back into the groove of things when I get back home and start to carry on my own life again. But this just hasn't happened for me yet. He is al I think about. And he started Nuke Power School this week and I literally haven't talked to him at all this whole week except good morning and good night texts. I thought the weekend would be better since he's not actually in school. I knew he had to study for a couple of hours, but nothing major. He called me this morning for about 5 minutes and had nothing to say. It kind of upset me because I haven't talked to him all week and he had nothing to say. If this is how it's going to be for the next six months while he is in Power School, this just sucks. I have just been so sad. And even after Power School, I still have to wait another 3 months. It's just this is really starting to get to me.... I'm trying to stay strong, I really am. I know this is the most difficult part because after this we will be married and together for a long time. Even when he deploys it won't be this bad because he will be 2 months on sub 2 months off. I could use an encouraging word. Any advice or tips?
