Getting back with your ex.

Me and my ex finished in August after 61/2 years  and at the time I was 10 weeks pregnant - fast forward until now we are still separated and he is seeing someone else and has been for 10 weeks as sad and pathetic it is I half want him back for me our daughter and the new baby but the other half just wants him to be sorry and to leave the other woman so I can let him feel how hurt I have been these last few months!
