After I had my baby, its been like he want to flirt with other female, talk to them on the phone. He put me on hold for hour just to talk to other people. We don't have any fun any more. He lie to me now.

Why are these thing happening to me? Do he want to be with me?

Have you talked to him, Is there issues with having a child?

Also... how old is he. Does he have any medical conditions... and has he had a recent complete physical including blood workup?
