Amalthia - your army guy is only away for five weeks, no time at all. Don't go out with the other two guys in that short space of time - wait and see what happens when your soldier comes home. You worry about him meeting other people on FB while he's away - don't you think he's having the same worries about you, since your relationship is so new (and how would you define an official relationship?!). You dating other guys while he's away won't give him confidence that you can be trusted to be faithful either - and you said in your other thread that this is only leave, he'll be on another tour of duty soon. If you are going to get involved with someone who's away a lot, faithfulness is going to be important to him. He's got enough to worry about in his day job at the moment, staying alive and looking out for his mates, without fretting that you might be seeing other guys. Don't do it. Wait for him.
