Dear Ashley,
I am SO sorry for your loss. The fact that you're in the Navy serving overseas must make it more difficult because (I'm assuming) you're not around family and friends. When I miscarried, my husband's (at the time) way of 'dealing' with it was to not talk about it. He withdrew, and I think it's the only way he knew how to deal with the miscarriage, me, and all the crazy emotions I was going through. Wave after wave of emotion would surface, and it took a long time before I could stop the tears from coming. There didn't have to be a trigger- they just happened.
I'm not in a position as a doctor to advise you on the grieving process, but I have worked very closely with one. I do know there's not a 'set time' for how long you will have these feelings of sadness, and that they're painful, normal, and keeping them inside only will serve to hurt you. Even though your boyfriend thinks it's in your best interest 'not' to talk about it because he thinks it upsets you, it sounds like it upsets you more not being able to talk about your feelings. I know it did with me. Although I believe your boyfriend loves you, and he is affected by your miscarriage, too, what he deems is best for you and your grieving process isn't what counts. It's what makes YOU feel better. I wish I could be there if only for a second and give you a big hug of understanding, comfort and friendship. The women here all know what it feels like, and I'd venture to say we all care very much about you and the loss you've endured.
Thank God there are places like this for us to talk and let it out. So many times those we love try their best to understand, but when they can't, they often close the door to communicating because they're at a loss.
It'll take time, and you'll never forget your miscarriage, but there are brighter days ahead for you. One step at a time, one moment at a time. Most importantly, as a friend and one who has lived it, allow yourself to feel for your own good. If you can't talk to your boyfriend, this wonderful place is here.
God Bless and I wish you comfort.
Ellen
