I am neither going to flame nor mock you.
Two questions: How is your Spanish? Can you fully communicate with her in her own language/? If not, you have a problem.
If you do, you might explain to her your reasons for being suspicious, not of her but of working girls in general. If she says, "But if you loved me, you'd know that I am different," you can kindly smile and tell her, "Ojala que si, pero necesitamos mas tiempo para saber").
I am not so cynical as to believe that they are ALL mercenary bitches who are only interested in your wallet. I do believe that in in very rare circumstances, it can work...at least as a long-term friendship if nothing else. I am not so jaded as to believe that working girls become so dehumanized that they no longer have feelings. You may very well have hurt hers.
Now, most guys will disagree here, but consider the source. Most (certainly not all) have suffered a string of bad or false relationships. Some have so little going for them that without the pay aspect, they'd never hook up. Sad but true...and I find it is often these guys who try to characterize all women as emotionless whores.

Yours might well be different.
My second question would be, "What do you really want?" Are you ready to completely turn your own life inside-out to be with her and her daughter? Are you able and willing to move to Costa Rica to be with her? If you cannot honestly answer yes, condemn any future love relationship to failure, because it is incredibly rare to be able to maintain a long-distance relationship, whether here or there.
My friend, I don't doubt that your love is real, but be sure that you understand the roots of that love and your own heart and mind before going any further.
PM me. I will be in C.R. in 11 days from today. If I can talk to her, I could be your Cyrano and pass along your message of love in Spanish, if you so desire.
You see, I believe that even putas need and want love. Shit, we all do, even those of us who are so emotionally crippled that we can find it in no other places than San Jose, Pataya, Angeles City, Rio, Buenos Aires, Prage or German FKK clubs.
Peace. ANd BTW, I am wearing asbestos underwear boys. Flame away.
