you are going to tell him to sit down you have something important you need to tell him and it is crucial he listens
then you will tell him I am just coming out of a very difficult relationship with Kevin that has bounced me all over the place I have no intentions of getting into another relationship with anyone - I may change my mind when the girls are a lot older - but I do not need another boyfriend I just need a friend - and being a friend means not hitting on me, pressuring me or making me uncomfortable tell him you don't mean to upset him or hurt his feelings but the choice is his - he can be a friend or he can leave and be an acquaintance
its not that hard Emily - the only thing here is how much do you care about his feelings? and if you do care because he is a friend then from his point of view you need to make it clear that you do not want him to be anymore than a friend otherwise in the long run he gets hurt more
so be clear - be straight - and be upfront
one positive thing in your life your posting on the thread seems to be settling down thats good
