No judgement here. I've made decisions I'm not proud of. I've been in your shoes before although the guy wasn't my significant others friend.

It's really easy to think the grass is greener on the other side. Especially when you're having issues and you've been with someone for a long time. The newness wears off. You see sides of the person you're with that you didn't notice in the beginning.

I don't think you're really as attracted to M as you think you are. M is attractive and he makes you feel good. It's easy to get caught up in the feeling of excitement and flattery that he gives you. He's new, he's mysterious. You haven't seen "those" sides of him yet. The biggest mistake you can make is getting these feelings mixed up with love. Another thing too is that if M were a man worth your time he wouldn't be after a girl who is in a relationship. Especially one that is dating his friend. He should have more loyalty to your boyfriend and more respect for you than that.

If you truly aren't happy then leave. You deserve happiness. But do it of your own accord... Not to be with someone else who may leave you missing what you had!

Best of luck to you sweetie
