Do i have a toxic relationship with my boyfriend?

I need some advice on what to do with my boyfriend. I feel like our relationship is pretty toxic but we both still love each other. First of all, he only really dated me to get over his ex. All of his ex's friend told me its true but my boyfriend still denies it. Second, we had a whole group of friends that kinda split in half over an argument and im still cool with some of the people in the other group and were becomming friends again. But if my boyfriend knew i was talking to people in the other group, he would be upset with me bc they dont really like him. Its understandable that they dont bc he keeps arguments going and starts them all the time js bc hes bored. I dont know what to do and i need some advice. My best friend said we should stay together bc we seem to have a healthy relationship bc we usually talk things out but it feels toxic.
