couple thoughts
brand new, sorta kinda relationships is when we are finding out about the other. Sometimes it's just not a good fit.
Sometimes we find out it's not a good fit because the person does something that we are not comfortable...it may not be anything bad or wrong, it is just something we aren't comfortable with.
I couldn't date a body builder, or someone who belonged to a faith incompatible with mine or had two young kids. There is nothing wrong with those things. They are just something I don't want in my life.
It's not a judgement on them or their quality as a human being or a partner, it's just not a good match.
It's hard when things don't work out like we wish they would. But it often is NOT personal. Just a bad fit.
