Over thinking

I have a bad habit of over thinking stuff when it comes to the man I'm talking too. I didn't start doing this until we slept together. & to be honest, I was a virgin til then. He was actually very sweet about the whole thing. He kept making sure I was okay and held my hand, thinking it makes me smile... It was like straight out of a girly movie or chick flick... But anyway, since then he has not treated me ant different than before. He calls, texts, calls some more. Lol. He'll even call while it work lol. (guy friend of mine says his "whipped" lol.)

I guess my question is how can I stop over thinking & worrying about something that doesn't seem like it will happen? I know why Im over thinking... I'm scared he'll hurt me like I have been before. 🐵
