We started dating shortly after she broke up with another guy. I had a hand to play in that so it did not fail organically. That was a mistake because she had no closure or recovery time. We moved really fast but she couldn't get over him. 

 Her friends didn't like me so they rekindled their spark behind my back. Disclaimer : the night she slept with him I found out she had went over to his house with a friend  and I told her it was over. She slept with him after i sent that message.

So we break up,  they rekindle and it fails organically this time. She was completely honest about everything that happened and what she was feeling at the time and why she made the decisions she did.  Brutally honest actually. 

Now she is completely different though.  Much more affectionate and attentive. She blocked him and doesn't speak to him. 
   
 She jumped through hurdles to prove that doing that to me was a mistake and that i was everything she was looking for,  just took her losing me to realize it. 

Now i do trust her. But i tend to over think stuff. And i catch myself lingering on the past or getting anxious when she is out with those same friends. I've never accused her off anything and honesty believe she's really in it this time around. 

 Any advice on how to shake the over thinking and lingering or any outside unbiased perspective that i might find useful.  First post ever so i apologize in advance if the format is wrong.
