Pregnant and scared! HELP!!?

I recently found out I may be pregnant, I had syptoms like nausea, food aversion, sore breasts, missed period and unusual discharge. I took 3 tests and finally came up with a positive. Im pretty excited and all and am feeling better about the whole thing everyday. I havent told my family yet but when I told my ex boyfriends ( we had just broken up when I found i was pregnant) he really didnt seem interested, he said he will support me but doesnt want a baby and refuses to sit down and talk to me. He keeps saying how scared he is but doesnt seem to realise I am just as scared. I have asked him to come to doctors appoinments and to see me and stuff and he just says hes going out with mates or seems really annoyed by me asking. I dont know what to do I obviously still love him and want him to be in my babies life but if he keeps acting like this I just dont know. Im so scared of being alone!
