Toxic friends or no?? Need a lil advice ❤️

My friends really hate my boyfriend but they won’t tell me why. They make up lies about me and him to try and break us up! And I don’t know how to deal with the situation.

They once told him I was with someone else when I was actually with them the whole day. They tell me all the time that he will not hesitate to cheat on me and that he probably already has more than once. They also say that he doesn’t even care about me and that he’s using me.

I’m so happy with him but because of what they say it makes me feel insecure, I believe in him because we talk all the time about that sort of stuff.

How do I deal with this situation as I’m very confused?? This has been happening for a good 2 months now
