OK, gentle time. I hate these …..
You don’t. You cannot get eat without opening your mouth, right? You cannot fall in love without opening your heart. Those are the stakes and you already paid. Might be regretting it slightly now, but all sales are final, no refunds given.
Love hurts. Accept that right now. It is also wonderful.
The obsessive stage will pass, it always does. You got it bad cause you are one of these “all in” people. You are in the very early stages of the relationship, otherwise, why would he potentially disappear? He can, however, be frightened off quite easily. So, to answer the question within your question:
Don’t go putting him on a pedestal too often. It may be good for the ego, but the air gets awful thin up there.
Make sure he has some space and you are not always hovering.
Relax. Take a deep breath and dial it back a notch. Not much, just turn it from 11 to 10.
For those curious as to the question within the question, it was obviously “How do I keep him?”
