Really need some advice on this situation??

Basically we were close friends but I moved away. I rang him recently and he was so happy that I called- he told me that I made his day and that no other friend cares about him enough to check up on him like me. We even started talking about the lovely memories we had together & he said that he's glad I appreciate them. Then I started talking about my new job- I said that the hours were f***ed up & he started laughing, replying with 'I thought you said you have more hours for f***ing now' even though I was one hundred percent clear in what I said. Then he said that he shouldn't be saying this & that he forgets how young I am. I just giggled telling him to wait until I'm a bit older.
Then a few days after our phone call I joined a messaging site & within minutes he had texted me a sticky with 'Hello' as the message (he has never ever texted me before)but I had lost his number so I asked who it was and he replies with 'it's me my darling'...

Opinions please??
