So, I can tell what it's really like for me, but it's embarrassing, and I don't know which placements cause it. Once I feel "allowed" to admit I'm falling for someone, I get so knocked out by the hormones involved in the "falling in love" stage I start acting like a stereotypical lovesick fool, thinking everything about that person is great. They can do no wrong. I hang on their every word. I am always excited to hear from them and panic if too much time passes. I can't sleep or eat properly and begin to lose weight. I do everything in my power to keep them from knowing how bad it is, so I've never been sure how much it shows. Eventually, if things progress between us, and he makes me feel loved back, that feeling eases into a deeper love. I know I've reached it when I feel a mixture of irritation and "d'aw" when he does one of his annoying habits, instead of not even noticing he can be annoying, and I relax and feel secure enough not to get jealous easily. I've only made it that far three times. Things would usually blow up in the middle of the infatuation stage. I've been married for a very long time now, so we've been through many other stages.
