Some guys can handle being in a relationship with an escort and others never will. My experience is that those who can handle it still have mixed feelings and sometimes get emotional. They feel left out. When you feel they are tilting and becoming moody and sad, you have to compensate, be super sweet, cook for them, cancel a date or two if you have two.
It also doesn't work if you say you love them but you do it for money. That's a HUGE turnoff for a guy, because you demean him. Tell him you do it because you really really like sex, maybe you are addicted to it but you don't need a shrink, you just need to do it. And tell him how lucky you are to have found a man like him. Just never talk about money with a man, make them feel they are the breadwinners.
And if this is not enough, look for another boyfriend who is OK with it. There's many great men out there who just love it and if you practice you will meet them. If someone asks you out on a date that's a good sign, but tell him, listen I am open to a relationship and you are a nice guy, but i love my job and want to keep doing it. Would that be a problem for you? If they say yes, give them an overnight half price and go play girlfriend. There's quite a few guys who just want this.
