I agree. It's really hard to disconnect your heart from your brain. I am struggling with this myself after a little over two months post-breakup. Time is the only thing and it's hard to be patient but it's best to do so.
Temp,
I'm new on here and posted a thread about recovering from a Narcissist (my ex-girlfriend). I have read your posts and find them very encouraging and helpful. Best of luck in your continued recovery.
