((doggiedo)) - on a lighter note...I almost typed doggiedodoo lol. I know you had another thread, so I missed why you wanted to break up? What are the reasons? Break ups are tough and for some its normal to flip flop with feelings and doubt. One minute you're confident and the next minute you doubt yourself. Also hard when you feel you lost your best friend too.
Its hard to think logically when you're all emotional. Maybe make a list of the pros and cons of the relationship .....whether this has a good future or not. In the meantime, stay away from getting intimate during this uncertain time, because this prevents both of you from making a logical mature decision. This way you won't continue feeling hurt and prolonging the grieving period. Some people can do the 'friends' thing but its a long process. Yes the 'lonely' creeps in at night doesn't it? Don't beat yourself up.
