yo sometimes SITTING DOWN AND CHATTING is not realistically an option when one party is unwilling and also some relationships are pretty messy to get out of and it is kind of something you have to work towards and i actually think that CONNECTING WITH SOMEONE ELSE is what pushes a person to be able to see that something they have is over, not the other way around.
Okay, first of all, if the relationship has degenerated to the point where I can't have a chat with my significant other over a major fundamental problem in the relationship in any capacity or medium, then the relationship is pretty much over because if that's the case I guess that would mean that said partner is dead or something.
And unless it's an abusive relationship, there's no such thing as 'messy to get out of'. And yeah, the thought occurs as if what if you're living with said partner and you can't just break up and leave because you share the rent or something, then yeah, that's the only messy scenario I can think of, but considering all of this, it's relatively rare.
And yeah, connecting with someone else takes time, enough time for me to call the partner up and tell them "Hey look..." before I just go out and bang someone.
Seriously.
