@monicasmith24,
The fact that he found you so easily and quickly means two things - both of which are troubling :
1. you didn't make yourself anonymous or untraceable enough
2. that he was seeking you out and is basically stalking you.
It'd seem to me that people the likes of him you'd want out of your life. I hope that you aren't corresponding through FB or other social media?
Hopefully, since then, you've found betters way of resolving your romantic entanglements other than by cheating.
