It means it's time for them to grow up and it's time for you to let go.
i would call it a boyfriend / girlfriend. You two are not yet engaged and are not married. when you have a boyfriend / girlfriend you are supposed to be "promised" to them.
That depends on where you fit in to the relationship.If you and your boyfriend have made long term commitments and have promised to be with each other and no one else. Then it would be cheating.But if you and your boyfriend are just dating and have made NO commitments, he probably sees you as just another girlfriend and that would NOT be cheating.
You don't get him because you have a boyfriend and he has a girlfriend and you guys shouldn't be talking because that's wrong.
If the day out has been planned for a long time or if the girlfriend is arbitrarily asking him to do so, he should probably explain his loyalty to doing what he promised. However, if the plans are not very formalised or if the girlfriend has a good pressing reason for asking for the cancellation, it is probably worth doing so. There is no single answer; it does depend on the context of the plans and of what each person wants.
I believe you are referring to Ayame, whom Koga promised to marry
Assuming you've already apologized and promised not to do it again and she's still on about it... dump her and find a more reasonable girlfriend.
It means his girlfriend has discovered what he was doing and he has promised her not to contact you again.
Rusty James had promised his girlfriend, Patty, that he would not drink alcohol or get into any more fights.
Tegan Coutts and her boyfriend Jonas Jew
It was probably hard. He left home because his parents promised the family fortune to his older brother.
Easily do something you promised you would never do. like tell her deepest darkest secret.. No that's wrong... if you are single and she has a boyfriend kiss him....and tell her that payback sucks..or do something that she hates.
If he doesn't call you when he says he will and/or misses a date that he promised to make. Or of course if you catch him kissing on some other girl.
