Difficult to say.
People, being people, can say "Nice meeting you!" as they leave, and hope they never see you again.
The phrase "I look forward to seeing (hearing from, meeting) you" is a formal expression in business letters. It does not really mean that the 'writer' (often an automated computer response) is staying awake at night longing for the wonderful day to come.
On the other hand, the use of the formulaic "look forward to," with the grammatical error ('see' for 'seeing'), and the use of "dad" instead of "father" suggest to me that the writer probably meant what he wrote. But the reader might interpret the formula "look forward to" as a formal reply with no genuine desire to meet him.
The reader and writer could fall out because of a linguistic misunderstanding. I hope they didn't.
