Why is my ex-boy answering me through facebook statuses.?

Ok.First off this is going to sound extremely immature, and I have deleted my facebook because it was impeding me from moving on. ( months ago my ex and I became friends after 3 years off war(i kissed another guy when we dated at the age of 18). It's been crazy ever since. Its long distance so it really hard( he lives in Dominican Republic and lives across the street from my family...NOT GOOd!)Ive been loyal the last nine months bc ive wanted to be...we were just fwb so i knew he still was doing his thing...but he causes me such heartache! Two weeks ago I had enough of his bullshit and so I facebooked him and said its I want nothing to do with him and to stope leaving me comments every few days.We used to talk all the time..but I def know i worked harder then him. Anyway since Halloween I have distanced myself and have had a very active solcial life. Anyway i called him less because I knew he it hurt me to know that he liked me, but still wants to date another girls.I started texting him and calling him about once a week.Anyway he wont comment my pictures which he never did on any social site before..He would make lil smart aleck remarks if i said im going out!He then started posting statues that said he was going on this weekend! On tuesday! it was driving me crazy, because I know he has commitment problems and all the stuff but he knows I love him. He is so insecure.What drove me crazy was how he posted pictures of when he picked me up from the airport on Aug 21! I was not in them of course..put he posted the ones I took of him carrying my suitcase...and then we talked that night and he asked me if i saw them.Anyway since the fight two weeks ago...i havbe had withdrawel sometimes...and Ive been freaking posting facebooks status...not always about him and Im noticing a very sick pattern. If i say a saying, hell say it next week. He re posted a saying i had put like too! He has been posting romantic song lyrics.AHHH!!If i use a word in a saying, he answer it back using a the same word!$ days ago i mentioned i had a new guy and then he posted a song saying Your boyfriend is a fool....I'll steal you...That was yesterday!! It was driving me crazy because I'm just so mad at him and I finally had enough of his games. So i cant get my self to call him..and he def wont since he is so prideful!...Im sick of it so I'm taking a break from the internet...but someone please tell me what doe sthis mean??????/
