My FP as of now is this guy I have been hooking up with. I respect that we are friends and he doesn't have interest in me romantically but I have such INTENSE feelings about him. Not even romantic just that I need to always be talking with him or see him and he recently moved to college from being a commuter so all this week I've been feeling abandoned and I'm scared he's going to find another girl he ACTUALLY likes romantically and just leave me. 
The last FP I had was my ex boyfriend probably; I feel a lot of similar feelings and have the same kind of behaviors when I was obsessed with my relationship. 
What do you do to make sure you don't fuck up your relationship with your favorite person and drive them away? How do you contain the intense feelings?
