I feel so heart broken the guy I have been talking to for 4 years now we tell each other everything we were thinking about taking the next step and dating me moving down there with my daughter and seeing how things would go I finally found someone to take over my lease and he found out 3 days ago he has a new born son the girl didn't tell him until she was at the hospital. I've never felt this feeling before
