How many times will he do this.....

I have been feeling really good lately. I am a month in from NC. This is kinda of our pattern for the last year I have broken things off about 4 times before and never did we go a month withought speaking. Im different this time im stronger and feel REALLY ready to move on with my life withought this loser bringing me down all the time. I have been reading ALOT about narcissism this forum has helped me soo much, everytime im sad i will just start reading and realize I wasnt alone!!Anyway I have been feeling alot of anxiety because the fact of how long its been and I kept wondering will he contact me? Maybey this time is different like he really will leave me alone and stay with his wife and family and be happy. Well that didnt happen last night he messaged me telling me "He was thinking of me and misses me" I didnt respond but now he has been on my mind all day and I couldnt sleep last night just thinking of his message. Its driving me crazy!! His wife just moved back in the home shouldnt he be worrying about her and leaving me alone? I swear the guy has a sense that im moving on and feeling happy again. I guess I just want to know if anyone thinks he will keep coming back even though I totally ignore him.... I dont want his hooks in me anymore and i know him messaging me is for his satisfaction ONLY!! I just wish he would leave me alone..
