<human>: Background: Found my boyfriend's online dating profile on his phone and I'm at a lost on how to bring up the subject. I feel upset, sad, and angry, but I don't want to project these feelings into an argument. I just want to communicate that his actions hurt me, is unacceptable in a relationship, and thus, I will probably ultimately end things as I clearly have trust issues with him based on my own actions; I don't want to point fingers or play a blame game as I realize my actions are not conducive to a healthy relationship either. I will give him a chance to explain himself, but I just really can't fathom an excuse that would make his actions okay in my books. I need help on how to go about this confrontation in a mature manner.

I have a terrible time with confrontations, but I am the worse when I have to instigate it. I often freeze up, choke over my words and lose my train of thought. Or I'll end up rambling too much and go off-topic. 

**What are some tips/suggestions you guys have to confront someone in a manner that is effective yet non-accusatory? This could be timing, location, tone, choice of words, etc.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Snooped on bf, found dating app, need help to confront him in a mature and effective manner that communicates my feelings/thoughts and maybe ultimately end the relationship.
