Still confused

Ok so im now 22 weeks pregnant and a single mummy, I totally fell for the guy, soon as I told him I was pregnant he ran ( he has a 5 year old son who hes brilliant with) he told me he wants nothing to do with baby. So recently he txt asking how I was, a few txts were sent that was a few months ago..hes now saying hes totally confused and doesnt know what to do, and doesnt know how he feels, why is he now saying this after saying my baby wont excist to him...I just dont know what to do..I need to know where things stand whether im going to do it alone or whether hes going to be there, its hard to cut all contact :(
