No, no, no Mammar - if he hasn't got in touch, he's not interested, sorry - the lost phone I can almost guarantee is an excuse - he backed off, then decided he fancied a bit again so got back in touch, then changed his mind again. Unfortunately, even if you do contact him, I bet he says 'it's not me, it's you' or 'I'm just not ready for a relationship' - whatever he says is just likely to leave you wanting more answers. Try to move on - sorry if this sounds harsh but it's true. Good luck x
