Re: What would make a guy take decesion at his own?
Nothing you can do deserves a goodbye without a backwards glance.
That said, everyone has their own predefined notions of they will or will not stand for.
If they're serious, then yeah I guess cheating can come into it. Repeatedly doing something they asked you not to do, perhaps talking to certain people abt the relationship as girls do and they not being comfortable with it
If theyre not serious, then almost anything. Especially something which makes u less physically attractive to them cos thats all they were in it for
