Personally for us, no. You teach people how to treat you. If you tolerate somebody breaking your trust you are teaching them that the behavior is acceptable and they never learn a valuable lesson. They never learn that it is unacceptable to betray people they love and care about like that.Trust me, I understand being in love with somebody so deeply that you can't fathom not having them in your life. The hard truth is that most likely that person will repeat the behavior and hurt you again if you never give them the chance to deal with the consequences of their actions.Take a break from them, focus on loving yourself and respecting yourself. You will attract people who love and respect you and treat you well.If they learn their lesson and change (and they are still worth your time) then they will come around. Who knows, maybe by the time they come around you may have grown enough to realize that they are not the right fit for you, or you realize that this is something that can make you guys stronger in the future.It is very hard to clearly assess relationship while you are still in it. Space and time will help you be able to focus on your own priorities. Emotions make everything very foggy, when you feel like you are losing somebody important to you there is a physiological reaction to the stress and it makes you want to do anything not to lose that person. Only space and time away from this person will help you get your priorities in check and come to a solid conclusion about what is the best for YOU.
