Boyfriend broke up with me because I could not offer blowjobs ??

I (F)36 and (M36)I understad men love sex,but to an extent of disqualifying you.if you dont meet his sexual expactations?Am a sex worker of course and its very clear on my ads that I dont offer blowjobs but he became my client ayways.He got attached and we started dating,all was fine.then up until he came back from his vaccation,he greeted me as usual and told me about his comeback,of course earlier onI wanted to end the relationship too,because I was not happy,with our communication skills..but he begged me to stay.....I stayed anyways...and he knew very well that am a prostitute.....and he said he had no problems with that...Now today after he came back from his vacation he asked me to meet up,but only for an hour and I asked why for an hour thats when he said he wants to move on,he wsnts to end this...they is no sexual compatibility...well I agreed thats his choice...but why now after dating me all this while?Men!we will never fully understand what they want exactly and what they are thinking.
