Hard time undstanding mother of my childs signals

Me and the mother to my unborn child mother had separated she is due in April, Im planning on doing everything for my baby, but she is seeing someone else, and she is scared and just cant stand on being alone, I can tell she hurts but I feel I do worse. I cant give up on working things out with her, no matter what. I just dont know when to really move on or not, Everyday I cry over this and realizing Im going to miss a lot of time with my baby and moments of him growing up, I dont know what to do and have been the most depressed Ive ever been in my life.

This is hard talk to her, tell her how you feel about seeing the baby you have rights to the baby as much as her. Dont be harsh about it or upset her but tell her how you feel about the baby. If she has already got someone else this is the right time to forget your relationship with her and think about your child.
