Write a break up text to bf because we had an argument about how he thinks I will cheat in the future with the “right circumstance” and that he doesn’t believe me or trust me

Hey [Boyfriend's Name],

I'm sorry things have to end this way, but I can't be with someone who doesn't trust me or believe in me. Our argument about your doubts and suspicions has made it clear that we're on different pages when it comes to our relationship.

I have always been honest and faithful to you, and it hurts me to know that you think I would cheat given the "right circumstance". Trust is the foundation of any relationship and without it, we can't move forward.

I wish you all the best in the future, but I think it's best for both of us to go our separate ways. Take care.

[Your Name]
