I really trusted this girl that I was dating and I shouldn't have. She was so nice that I couldn't help but trust her for the whole time.
I really felt confident that I could trust and love this girl that I used to date.

You always hope that is the case. Sounds like it didn't turn out well. I'm sorry.

That's terrible and really not fair to you. I feel so bad you had to go through that.
