You're likely a very sweet person. Some people (men and women, both) are dishonest users and they'll take advantage of anyone and everyone they can. To top it off, they'll blame the people they victimize. Their opinion of you is worthless. I think you are right to be cautious at this stage of your new relationship. From now on you might want to go slowly, and allow people to earn your trust through demonstrated honesty. I wouldn't give a man my money, my time or my body too quickly, especially nowadays.
