When to let go?

I'd say if there is more bad than good or if you are even entertaining the idea of being with someone else then chances are.... it's over. Letting go of someone you have shared everything with for a long time can be tough. That's the recipe for a lot of bad relationships... Two people together for the wrong reasons.

At the end of the day you have to ask yourself what will make you the most happy. Not content or compromising... happy. If you do break up but were really meant to be together, you will end up together. Just be nice about it.

Of course. Why leave someone hanging, thinking everything is "peechee", when you have fallen for someone else, Let that person go.

I am currently in a similar situation myself. What I decided to do was I asked my boyfriend to give me an entire week to myself. I asked him to not call me (unless there is an emeregency) and to just give me a little space. I assured him that I was not breaking up with him, but that I needed some time. I see it this way...if I am going crazy all week cause I miss him so much then I still want this relationship, but if I find that I am happier without the stress of the relationship and I am enjoying my time alone then I need to end it. I am on day three of my week and honestly I feel more relaxed than I have in months so...
