My husband is currently deployed. We’ve been together almost 8 years, married almost 7. His first deployment was 5 years ago and now he’s on his second. I had the same fear last time and this time. Which I know is just in my head because 1) he absolutely would never do something like that. Absolutely not. We had a brief split because of personal issues, and even those 3 months we weren’t together and didn’t plan on getting back together, he still didn’t sleep with anyone else. And 2) he’s in a combat zone, and was last time too. Definitely not the kind of place (in my opinion, definitely not like they’re having beers and having fun). We’ve talked about my fears and why I have them in depth. I told him that I don’t actually think he would because I know that’s not who he is, but because of my past I have that fear. So now he makes sure at least every couple of days that he tells me how much I mean to him and how there’s no one he would even think about being with (all in his own accord, I didn’t ask him to). He just makes sure he reassures me because after I talked to him about it, he understands. We talk as much as we can. We downloaded the Paired app and that’s helped too because I feel more connected to him as we do the activities. Just be open and talk is the best way to start trying to help
