I met a guy through fb. He has quite a number of mutual frds. So I accepted his friend request. He has always been asking me to see outside but i was always making excuses as I just recovered from a year heartbreak and being careful. Last month he was in a situation to come to my work. He asked me to see during my lunch break which I agreed. The lunch feels a bit awkward for me as I have never dated a stranger before but we managed to chat about likes and hobbies. He texted me minutes after it that it was nice seeing me and i replied.
He didn't texted me for days and so I thought he wasn't interested in me. But after 3 days he send me fb message if we can meet again. I was a bit busy at that time and told him I will get back to him but I wasn't able to. after a week he ask me when I finished my work and he is coming to place near it and if I am interested in joining him. But I had to go back home early that day because and so I had to declined again. I apologized him a lot which he says its ok.We always chatted after that and even joke. But lately he stopped texting me and I was the first to initiate the conversation.
What did I do wrong? Did I give him the impression that I don't like him? Or do I seem too busy that I lost interest in me?
I can't stop thinking about him. What can I do?
