Boyyyy... I get it, you're under a lot of stress both internally and externally. But you shouldn't have said the things you did, you could have conveyed your feelings in a different way...
*sigh* he's not a bad guy, and I don't hate him, but that definitely cost him dearly. I really hope he gets a happy ending with someone that has the same life goals as him.
TBH both their relationships were toxic, ML was too dependent, refusing to have other relationships holding her emotionally hostage... FL simply is completely passive in her relationship, making the other guy do everything.
I hope they both do some self reflection and maturing before venturing into their own relationship together. I also hope that their current partners will find people who are in the same wavelength as them.
