So my 6-year relationship is coming to an end. Although it's mostly a mutual agreement, both of us want to be together but have irreconcilable differences in lifestyle choices. We've lived together for about 3 years. Yesterday he suggested that I might have PTSD from an incident that I've talked to him about. He tried to talk to me about it and all it did was send me back to those feelings I had the time of said incident. And I just started crying and when he tried to console on me I pulled away from him. At that point I had pretty much switched on him. He went out to a friend's house last night, and I haven't heard from him since. And this morning I keep trying to text and call him and he's not responding. I feel myself slowly turning into that crazy ex-girlfriend mode where I just freak out and think the craziest thoughts and have the stupidest impulses to call a million times and send a million texts and even drive to the friend's house to see if he's there and I don't want to. I don't want to feel this way. I don't know how to stop it.
