Why does my ex ignore my texts, but like my facebook posts?

Me and my ex broke up 3 years ago. Ever since we broke up we have always told eachother we still love eachother and miss eachother and all that good stuff. Well, a few months ago we decided to see eachother to see if there was still a "spark" between us. Everything went well I thought, we kissed good bye said our I love yous and she left. Well a few days later she got shipped off cause she is in the military, and I sent her a text explaining to her that I still loved her and asked if she thought the spark was still there, she said she loves me but idk..so I gave it a few days and asked how she felt about me and she read it but no reply. Well a month down the road (she's still shipped ouut) she's liking my facebook posts, pictures and statuses..but she can't send me a reply to a text? What does this mean??
