I [24F] found out my boyfriend [26M] liked random girls’ posts. Is this something we can move forward from?

My boyfriend and I have been together for 8 months. He has always treated me like a princess and we had a very healthy relationship. We argued very rarely, and our “arguments” were just conversations, except…

Recently while we were speaking on the phone, I was bored and went through his following, and saw there was a girl he didn’t know who he followed, and he liked a very recent post. I was in shock, he had told me prior he didn’t feel comfortable with me allowing random men to follow my private account, so I started to not allow men I didn’t know to follow me. Him doing this made me feel stabbed. I was in shock.

We immediately took a break from the relationship for a few days, when I asked him why he did it, he said ashamedly that he didn’t think through it, and it was because he saw large breasts so he just did what he did. I felt disgusted, it’s like I didn’t know him. He alleges he didn’t mean to make a move on anybody and completely understands how I feel.

I told him if we were to continue the relationship, it wouldn’t be the same. I’m a person who takes a long time to love and we hadn’t even said I love you, but I was close, and it’s like I’m back to square one with him, because I’m not sure if I can trust him.

I want to believe he’s able to change but now that we’re back together I get more and more reels that say men that do that never change. I told him that it’s gonna take a while for me to completely trust him, and (I say this with shame), I require him to stop following all the girls that didn’t follow him back, which he said he’s very comfortable doing and willing to do anything else to save the relationship.

This is a bit off topic but I think it’s very ironic that I’m an atheist, he’s Christian, and he talks a lot about how people should have self control and all but then he does this. His words don’t match his actions. I told him this, he said I was right and he wants to be a better man. Every time I point out his hypocrisy in this subject he never complains, he recognizes he did wrong.

Again, I’m very suspicious and I don’t trust completely his words, I’m afraid I’m increasingly emotionally detaching from him because I truly don’t know if he, as a man, can change. For example, I’m not even jealous of anything anymore, I don’t really care where he is, I don’t feel like sharing about my day, I don’t send him as many texts anymore, etc

Do you think men can change? Do you think this wasn’t an indication of possibly future cheating? Am I throwing away a good relationship? He already knows that I gave him the benefit of the doubt once but twice would not be possible for me

Edit: many of you came for me in the comments. I get you call this an overreaction from my part out of childishness and insecurity, I’m glad the women in the comments can live with their men lusting after other women but personally that makes me feel sick. I’ve decided this wasn’t full on cheating, it was a break of trust, and I’ll give a second chance to the relationship but slowly
