Am I being unreasonable, or is this relationship beyond saving?

I 27F am considering leaving my fiancé 24M, but I’m struggling to figure out whether I’m seeing things clearly or letting my emotions get the best of me.

Last night, my fiancé went out with a friend. When he got home, he told me about their night. His friend recently went through a breakup and apparently saw a woman who looked like his ex. My fiancé said his friend asked whether he should get her number.

While telling me the story, my fiancé mentioned there were four women at the table and said the woman his friend was interested in was “the only one with potential.”

That comment bothered me. We have major trust issues because I caught him cheating a few months ago. To me, it sounded like he had been evaluating the women at the table and deciding which ones were attractive. I also felt like the “potential” comment suggested he was trying to decide whether he would be interested in going over to the table with his friend to engage in conversation with one of the other women there.

I asked questions about it, and we ended up arguing. He said I was overreacting, had an attitude, and should trust him. I felt like he was dismissing my concerns, especially given the cheating.

The argument escalated, and he put his hands on my neck to make me stop talking and leave him alone. Our 8-month-old baby was present.

The next morning he texted me an apology saying there were no excuses for what he did and that I didn’t deserve to be treated that way.

So my question is:

Am I being unreasonable for questioning his comment and struggling to trust him after cheating?

I’m looking for honest feedback, even if it’s hard to hear.

TL;DR: My fiancé cheated on me a few months ago, so trust is already damaged. Last night he told me about being out with a friend and mentioned a group of women they saw. He said one of them was “the only one with potential,” which bothered me because it sounded like he had been evaluating them. I questioned him about it, he said I was overreacting and should trust him, and the argument escalated until he put his hands on my neck to make me stop talking. Our 8-month-old baby was present. He apologized the next morning and said there were no excuses for what he did. Am I being unreasonable for questioning the comment and struggling to trust him after cheating, or am I overlooking bigger problems in the relationship?
