Help with love ❤️

So, where to start... so I’ve been in a relationship with my boyfriend for almost 5 years in April. But the last couple months/weeks haven’t been as good as normal. We fight daily but make up hrs later. But I’m also feeling some intense feelings for his married friend 🤦🏼‍♀️ I think I’m falling out of love with my boyfriend now. Help. I lived with him since I was 15, I don’t have family or anything besides his mom. And he was a virgin when we met. I’m to heartbroken/unsure to break it off. I’ve tried a break before and went bad, he couldn’t sleep or eat without me. And my stupid ass went and slept around and realized that I was wrong wanted to be with him.(he took me back) But Now, I have this feeling again like I don’t know if I wanna do this anymore or just settle 🤦🏼‍♀️🤦🏼‍♀️🤦🏼‍♀️🤦🏼‍♀️
