Helplessme, only your BS can tell you when its too much. If your join date is anywhere near your dday, then you're in the very beginning. You just need to be patient, proactive, and consistent. For a long time, the majority of my texts and check in photos to my BSO went unanswered, but I kept at it. And with time, transparency and consistency, I was able to begin to build back some trust.
Talk to BS, ask him what he needs from you each day to feel safe. And don't be discouraged if he doesn't text back. It may be very hard and painful for him to have to respond.
