<human>: Can you succinctly summarize the text in 1-3 sentences?

2 years into a wonderful relationship, here I am, convinced she has been cheating on me periodically. To be honest I don't care that she wants other men, that is inevitable in any relationship, it is the deception I lament. She has told me from the beginning that most of her friends are men. Only recently has this become an issue. Everytime she's gone out over the past 3 months or so, less than ten times, she has ignored me at the end of the night when I try to contact her. I've asked her on multiple occasions to at least contact me at the end of the night after she goes out. Everytime she has an excuse as to why she wasn't able to text or call. The next day I question her and she is always defensive, questioning my intent, saying I don't trust her and even threatens a break up when I push for a real answer. I want a relationship where honesty is key, and feel as a team, where we can be genuine with each other about anything. Unfortunately I do not feel as though she is being genuine with me. Am I neurotic? or is she hiding something? I really need some input here
<bot>: I've looked through her texts and seen conversations with her slutty (girl) best friend about hooking up with guys
