Unsure about whether to end my 10-year relationship... just venting.

I [30F] began dating my fiancé [30M] a decade ago. We had mutual friends but had never crossed paths until one day, after engaging with each other's posts on social media, he reached out to say I was cute and wanted to get to know me. Our connection blossomed into an engagement, and we've been engaged since 2018. However, during our relationship, he has crossed boundaries that I'm uncomfortable with, such as suggesting to old female friends that they should hang out like the old days. One significant boundary for me is that I dislike him interacting with women’s pictures on social media, especially since that’s how our relationship started. I also find it disrespectful when he likes women’s selfies or bikini photos while we’re in a relationship. I've explained how upsetting this behavior is for me and how it may appear to others. He apologized sincerely and even stepped away from social media for a while, but when he returned, I discovered he was still engaging in the same behavior. In September 2024, when I confronted him, he expressed remorse again, but I felt frustrated and told him I couldn’t accept his apology since true remorse would mean he wouldn’t repeat the behavior. I considered ending the relationship, but it's been ten years, and I’ve never been on my own. Our 10-year anniversary in January 2025 was disappointing. I surprised him with a sexy dress, but his brief response of “yeah” left me holding back tears all day. Unfortunately, I discovered again that he was still liking and interacting with women on social media in January, including a specific woman we both worked with whom I’ve already expressed my discomfort about. I do everything for him—I cook, clean, and cater to his needs. I don’t have male friends at work because he feels uncomfortable with it, claiming that my interactions imply I have an "interest" in them. I have no friends, and my family isn’t supportive, so he is my only source of companionship. During the pandemic, I created a gaming Instagram to try to connect with others, but that seems to bother him too. I could elaborate further, but I’ll stop here. I recognize what I need to do about my situation, but I would really appreciate some outside perspectives.
