So the other day I started having a problem with my messaging app force closing. I am able to text anyone in my phone, except the one person I text most, my girlfriend. The last message I was typing to her, I never finished and is in there as a draft. I am guessing maybe this is causing the problem for whatever reason, and I'm guessing I can fix it by just deleting all threads, but I don't really want to do that unless I have to. Anyone know what the problem would be?
