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?"
This is what I love most about you MM
You got to the heart of the question. You've really helped the reader have a concrete way of dealing with her feelings. We all worry at some point if the one we love will ever leave. At times it can be really tense but after time and with trust it goes away.
Good Luck to the OP!
I would say this means you should proceed with caution! I have had the same thing happen to me before. The feelings you are experiencing may only be lust and chemical attraction. If you move too fast, you may overlook some potential flaws or red flags.
Enjoy yourself, have fun, but until you have passed a 6 mo. , 12 mo. or more mark and know more about his character, consider this obsession to be exactly what it is, lust. Not love.
Oh yeah, and don't let him know about your obsessive-ness or he may think you are clingy when you really are not and bolt. Spend more time at the gym and burn off that extra energy :)
