I have been in contact with this guy for 3 months now where he was introduced to me through basically his ex girlfriend. He started calling me almost everyday and we spent time talking to each other and I met him once where I spent a few days at his place. I did not really feel attracted to him at first but eventually I felt that I was getting closer to him and as he kept calling me everyday and saying that he liked me very much, I thought he was equally attracted to me too. But recently he found out that his ex girlfriend has met a new guy and he became very jealous to the extent that he kept calling her and was unhappy about her meeting this new guy. He even shared with me his concern and I eventually realised that he did not feel any spark with me and was just using my time to listen to him every day. I had to make a difficult decision to ignore his calls as I got hurt that he feels there is no spark between us but it was very confusing for me when he kept saying that he likes me very much repeatedly. I would like to think that he is a nice man but I now feel cheated when he seems to have not moved on from his ex and has been using up much of my time to just listen to him talking.
Any thoughts? I know it will just be logical to stay away from him but I also don't want to be rude not to answer his calls.
Also is 3 months too fast to ask someone if he wants to commit to a relationship or not since he has been the one calling me and wanting to talk to me but is yet to make up his mind whether he wants to get to know me better or not.
