Does it get better?

So let me start off by saying me and my bf have been together for 2 years. I noticed that he was following girls from TikTok and liking their pictures and stories it’s also not just normal pictures they are explicit. He said he will stop and he did. However, during the past 2 weeks he’s been doing it again however he says he’s not doing or that it’s some type of glitch. He also commented on a girls picture with 😍 and he said he didn’t do it he was like someone is probably on my account and when he checked it was only him so is he making this up or I’m being delusional. Would you still stay with this person? We agreed that TikTok wasn’t a problem even though it still kinda hurts but we definitely agreed that instagram is different. I told him to delete all the photos he has of me because I do send him dirty pictures. And he told me to delete his so I did. And now he hasn’t messaged me since 1 and it’s 9pm now

I’ve said so many times that I’m gonna leave if he continues idk how to leave i love him but I feel like im constantly finding the same shit I get upset about and it’s breaking my heart. Or im just being too sensitive and jealous and insecure

So tell me your opinion?
