If it was a troubling situation(s) then sure. Like for example if their abusing you or not treating you right. Well, you can leave anyone, but if you have something you share.. try to work out a plan and try to have time on it. I would in my personal opinion leave upfront without telling where you are going to go or tell him/her your leaving at all (in a abuse or Whatever similar situation)
Leave. Just leave. No one deserves to be abused by someone, especially someone they care about. You need to leave them before the abuse gets worse.
Just leave them and move on
all you need to do is just ......................................... RUN
no it usually is because they are seeing someone else or their scared of change.
Then tell that person if she likes you or just leave as is
If you know you want to and have to leave just do it - make a clean break and don't look back.
No, just leave them, and eventually someone will answer them.
Just leave and think of something at home or at your desk
you just have to tell them that you dont feel the same way
Just by writing to them as if they were there, they will still get a message from you. Some are set up to be sent to their email.
just try to get along if it doesn't work someone should leave.
Just leave it where it is and forgot about it. Then it is someone else's problem.
