Why do guys energy change after our first dates?

Anonymous
I had guys who spends so much time texting me in paragraphs to make me interested, charm, and feel connected. We would go on first dates and they still seem interested by asking me questions, compliments, or even hug me… but after the date… their texts are more dry, low energy… why? Do they lose interest after just meeting to get over the excitement? Is there anything I did wrong?
