<human>: Sorry for formatting. I'm on my phone here. So basically I'm in a 3 month relationship with a guy who we will call Evan. We have been doing well and I helped him get over what I THOUGHT was a one sided crush on this girl, let's call her Stacey. Neither of us liked each other so it was easy for me to give him advice on how to handle his crush on her. 

They haven't been in touch for about four months and only knew each other a month prior to him liking her, and she ended all contact with him. She recently re-added him and has been apologizing for how she treated him. He brought this up with me and I told him she did seem genuinely sorry (he showed me the text) but it was completely up to him what he did. She mentioned knowing about me and how she wishes she has the chance etc etc. He chose to remain friends with her but said he was in a relationship.  

I was OK with this until I reread the text. She had mentioned doing "something" together and when I asked him about it, he said she would frequently attempt having phone sex with him. That is none of my business but I feel annoyed that he decided to hide the fact that the crush was not as one sided as he made it seem. Is it wrong of me to feel a bit angry that he wants to remain friends with a girl who is making it obvious she wants him now and "missed her chance"? I feel insecure and like he isn't really over her and this will lead to me getting cheated on or broken up over...

Condense the text into a few key points
