Is it love

Met a guy online 3 years ago, we spoke online whatsapp for 8 months- I was in relationship so refused to meet him on few occasions.

We suddenly lost contact and after 3 years he reappeared in my life - now we hate 5 months together.

Timing was perfect as I just ended my relationship two months prior.

I'm often wonder if he taught about me all that time / why he really came back into my life ?

These questions have yet to be awnsered.
