<human>: Could you distill the essence of the text into 1-3 sentences?

So a little background I said more then FWB because the girl just got divorced in August and insists that we not term what we are as boyfriend/girlfriend which I am fine with. That being said we have been talking everyday and spend most night at one or the others place. Even she has admitted that we aren't really just FWB. I have been seeing her since the beginning of October. 

Now on to the issue at hand. I went back home for a week during Thanksgiving and she left for training (both military) which she returns from this Friday. Well starting Saturday her communication started getting off( like I said we have been talking everyday) and then yesterday she stopped responding all together. I have a suspicion that she hooked up with a guy she knows that lives there as she mentioned that it could happen before she left. If it did happen I have mixed feelings but as she has made it clear that we aren't in a committed relationship. 

She has stopped talking to me once before when we first started seeing each other because in her words "she liked me too much." Communication is definitely not her strong point. So how should I approach it? I have only texted her twice because I don't want to come off as clingy but I really want to know whats going on. Even it's that she doesn't want to see me anymore that's fine. It's the not knowing that's driving me crazy.
<bot>: My FWB has developed into a quasi relationship. I suspect that she slept with someone else and that's why she stopped talking to me. I have texted her twice, How should I proceed?
