<human>: So I met this girl and we hit it off big time. She's great as well as our relationship thus far. She treats me how I should be treated and I appreciate her for it. She's honest, kind-hearted, and genuine.

My previous SO was a really shady piece of shit and I never really trusted her. I've learned now that being with this girl that those trust issues are still with me even though this girl is not shady at all.

I always imagine the worst in my head and it's fucking me up. Just one example is.. 

"Hasn't texted back in 15 minutes?" "She's up to something"

I know that's vague, but it's just a little example of this thought process that I can't seem to shake. The instant theres any shred of uncertainty I can't help but to think the worst.

Also, she has guy friends. Everyone has friends of the opposite sex and I understand that, but I also find myself thinking that maybe her and her guy friends are more than just friends. 

I really like this girl and think she is special and I want to try and fix this.

Can you condense the text into three sentences or less?
<bot>: Met a great girl and we have a great relationship, but I can't seem to shake the thought process that my ex left in me.
