Right need your help me and my boyfriend have been having problems lately but have been ok ?

We have Had issues with each other and have been argueing but have been ok and getting past it all he was only talking about Xmas and the future the other day but all of a sudden he has gone really strange and doesn t want to talk to me when I phoned him and now I can t get through to him on his phone it is ringing once and then going to the answer phone , has he blocked me ? I am wondering but he is still msg in me on facebook and is still engaged on there to me so I am confused , he has been on whatsapp messenger but has denied being on there so I finished it but he doesn t seem to care but he said he does care very much an he loves me an will always love an that I am his life an he wouldn t risk losin me to be up to no gd chatting to some one else but the other day he was on there a lot and now he is on leave from work he is hardly on there so I am thinking is he with some one else who he has been talking to on there ? But then if he was then y is he still msg in me on facebook ? , and he said that he doesn t want people knowin that we finished and said that he was angry that I told my mate but I just needed to talk to some one and he said that I can delete him off facebook if I wanted to just incase I meet some one else cause he doesn t want me to rub his face init an he doesn t want to see any thing cause it will hurt him so I just really don t under stand
