<human>: Can you provide a brief overview of the text?

Me and my boyfriend have been together since I was in highschool. He has always been in the army since we've met, but he hasn't had to go away for this long a period of time before. He will be gone until December and we are very confident that we can make it through this. I'm doing ok so far, focusing more on my education and having a fun summer with friends, but every once in a while I get overwhelmed. Those questions pop into my head about talking to him too much/ not enough while he is gone and wether or not he will change for the worse while he is away. We have talked about marriage on and off and he even says he wants to marry me when he gets back. This is exciting news! But what of something changes? I guess my question is: How do I deal with him being gone when it gets overwhelming? I obviously can't complain to him each time I have a temper tantrum. He's under stress too and it's not fair to unload that onto him when he is in a vulnerable position.
<bot>: my boyfriend of 3 years is going to be overseas for 8 months. How do I deal with the stresses of him being gone while still being supportive?
