I know what you mean. I knew a married man like that - gorgeous with all the trimmings (educated, great job etc) but married with kids so i sulked for awhile that i couldn't find his single, twin brother but NEVER, EVER romantize your ex so much you wish they were back just to have someone with you!!! Spend less time alone - get involved with kids, a charity something far away FROM YOUR PITY POT! This too shall pass...
