Worried about heart break

Hello all. I am 16 and have been dating my girl friend for a years and 3 months. She is my first love. I am very deeply in love with her and 2 months ago she broke up with me for a month and it hurt more that anything. We are back together but within the next 2 years she is going into the RAF and will be going on camps in other countries and it will lead to the end of our relationship. I know 2 years away is a long time however I'm finding it very hard to date her knowing that it's only going to end with the same devastating heart break as I felt not long ago. So the way I think of it, I either have to go to the same sixth form with her and be heart broken now and be over her in two years time OR stay in love with her now for two more years and have to face her leaving me again now. But I don't think I can bring myself to end it with her now and even if I do I'll probably run back to her anyway. I am really lost and don't need this during my A-Levels. If I end it with her I won't be able to concentrate for fucking ages and my A-Levels with go south. The alternative is not being able to concentrate in Uni while she is no doubt being fucked by for RAF lads. And that fucks my head and do not know what to do. I fucking love this girl more than anything. HELP Godbless.

Hi! Is there any way you can stop worrying about "what if's" and live in the moment? Two years is a long time away. And there is so much joy and fun you two can have together, create memories, life long memories. Your break up seems to have created an anxiety for you about things you can not control or predict. In two years you will be more mature and have a stronger bond with her. I suggest you make a conscious effort to change your thoughts from "what if" to "what is". "What is" right now is that you love her, she loves you (she got back with you) and you have "time" to be together and enjoy each other. When you find yourself thinking thoughts about your heart getting broken, her leaving and other guys in your mind just say "stop" and change your thoughts to something like "we had a great time last night", "she is so funny and that is why I love her" whatever you need to do to replace your negative thoughts with current present positive thoughts. I fear if you break up with her now you will have regrets. That is why I am saying you should enjoy "today" and "what is". And what is, is that you love her and want to be with her. I hope this helps.
