Why did he have to do that to me?!?

earlier this yr,i was involved with this guy.we hit it off really well at the beginning and the sparks were there.he texted me everyday and we'll have great chats on the phone.i couldn't believe it but we had soo many things in common.he asked if i would like to be his gf but i declined cause i wanted to make sure that he's serious.he didn't mind and said he would give me time.throughout these times,he was being sucha sweetie but as days go by,he changed.he was in army and he still is and i understand that he's busy but he claimed that he's so immersed in his work that he didn't have time for me.i was as patient and as understanding as i can be but that didn't work.he told me he couldn't commit and wasn't the kinda girl he wanted.but he insisted on keeping in contact with me and wanted to go out with me but i said no cause i was really hurt by his hot and cold temperaments towards me and looking for me only when he "felt like it".after awhile,when he knew i was sick (to be cont'd)
