My boyfriend of three years had a fling with a woman in the early stages of our relationship. Am I wrong to feel upset that they keep in touch?

This only came to light a year into our relationship and he says she came on to him. He said after one night he put a stop to it and then carried on as friends. I now find out after we’ve been going out for 3 years she works at the golf club where he plays regularly and they keep in touch via text. He knows it upsets me particularly as this woman has a reputation of going after men who are already in relationships and is on her 5th marriage. She started getting my boyfriend’s attention by sending him naked images of herself. He says I should trust him but I’m so worried it may happen again particularly as they are now more likely to bump into each other. I thought she was off the scene a long time ago. I know my boyfriend has other female friends and keeps in touch & I’m totally ok with that, I too have male friends, but I have a bad feeling about this one. I feel awful for feeling jealous but so scared this will ruin everything.
