I dont know what to think ~ i'm crushed!?

my ex and i dated for a year and a half ~ the problem was that i'm in my mid 30s and was in a horrible marriage which made me scarred of committment again. my ex is almost 30 and is ready to find a wife. this caused many problems. in may we had a horrible breakup and we both said mean and horrible things to eachother ~ which is not like us atleast not like him, he always respected me and treated me right. after a month i decided to text him to see how he was ~ turns out within the month we broke up he got engaged to a girl he dated years ago (she now has been married and divorced twice and has 2 kids) and moved across the state. though i was heartbroken i told him i was happy for him. we talked his whole lunch break. he texted me that night but i didnt text back. the next day we texted during his lunch break again. i told him i had finally lost the 10lbs i gained while in school ( we both just graduated from college, thats where we met). he then said nice, and said i wanna see. he was wanting me to send nude pics ~ WHICH I DID NOT ~ then he asked if i was seein anyone and i said no and he replied so no sex for u, and i laughed it off and said nah. then we continued to talk until his break was over. that was on friday, monday i was hired for a good job and i was excited i was texting all my friends telling them. i texted him and told him i got a job (he had asked me the last time we talked if ive found one yet) his reply was hey i cant text u ~ i asked why? i just told u i got a job and he said because of the gf he didnt want no trouble. i was crushed, not because of his engagement but the thought of never talking to him again. how could he say trouble when he lives across the state, what did he think i would do get in my car and drive to where hes at? why did he do this, it doesnt make sense that one day we were getting along just fine and the next he doesnt want to talk to me. if it was because of the gf why didnt he say he couldnt talk to me the first day i texted him? this isnt like him and it hurts that he couldnt even say he was happy i got a job. i need some input please, i'm about to go crazy ~ i also made it clear when i first texted him i wasnt trying to get back with him or start anything, i was just seeing how he was.
