<human>: Give me a shortened version of the text

My gf's ex is one of my friends, they used to date on and off but nothing serious. I went through all the hoops of asking my friend if I could date her and everything. We clicked instantly talking for 8-10 hours a day non-stop texting, calling and everything. fast forward a week after our first date and she goes over to her ex's(my friend) house to talk with him, later that night she texts me that she isn't ready for a relationship and breaks up with me telling me that she still wanted to be with her ex and she ends up staying the night there, its been confirmed that nothing happened between them. This little instant pretty much destroyed me emotionally I shut out everyone for a weekend coming up with ways and a mind of thinking that we could still be friends and threw a wrench in my feelings for her. come the next week she tells me they never got back together and wants to have a second chance, and after a long apology and conversation I took her back. 

Fast forward 2 months, things between us are going great we are absolutely adore with each other and have barely spent days apart. I have kept her and her ex separate to avoid any awkwardness, the ex wanted time away from her, in order to get over her. A couple days ago my gf tells my they started texting one another again and they might hang out together soon to see if they could still be friends. At first I was okay with it, but today is when they're hanging out and i have this deep anxiety from what happened before. She confirmed with her ex that he has no feelings for her anymore, but I can't seem to get the thoughts out of my mind.
<bot>: Girlfriend wants to try and be friends with her ex(a friend of mine), but I can't shake the anxiety of her breaking up with me the last time they were together to hang out.
