He hasn't blocked my e-mails. In fact he is answering them. He blocked me on MSN, because he is trying to get over me (when I returned a birthday gift he was shocked, refused to take it but then said reluctantly it would be better that way").
He learned yesterday that I had some health problems. He wrote an e-mail instantly. Not getting an answer he sent me a sms which I answered. He sent me a e-mail this morning asking for more details and telling me about his coming week-end.

I agree with being cautious but why is everybody saying I should forget him and that he doesn't love me ? How do you know for sure? I don't. He doesn't. I am not going to forget it now (next week maybe if things don't move). I was asking for suggestions about the best behavior to find out if he loves me or not. Keeping in touch or stopping any contact. He is the kind of guy to retreat in his shell.
