Relationship advice (honesty accepted)

Stephanie

So me and my girlfriend have been together for almost 4 months. We say we love each other and everything but we don’t see each other like that because we are both in the Army. But when we do it’s wonderful. But when she went home for a while she told me she kissed a girl but the kids didn’t mean anything and that’s all it was just a kiss nothing more. I haven’t did anything physically with anybody but I do get attention from other people and she do the same. But we tried breaking up but we always get back together. Our trust is really bad and we know it but we don’t know how to fix it knowing our distant. I need help on what to do
