So me 34 male match a chick on tinder 26f. We were messaging normal stuff till she told me she was an escort. I was going to say no but it’s been a minute and she was almost charging me nothing so I was like what the hell why not. I looked her up on escort sites and she charges way more then she charge me so little confused on that. The night of I came over we hung out a bit then did the deed. After we where done she said next time it’s on her it’s free.i was like ok shit free sex. Seen her a couple times and lately she has been asked if I can stay and chill after we are done. If I’m not busy I do because she is a little wierd but not in a bad way so I don’t mind. I’m not trying to be in a relationship with an escort but I feel she catching feelings how do I tell her no about a relationship but we can still be fwb if she want ? Advice would be nice.
