I understand how you feel. I dated a guy for awhile and ended up pregnant. I broke up with him and he couldn't seem to get the hint that I didn't want him around. He would call non-stop. He would threaten to kill himself...Threatened to kill me once too...While I was pregnant...So not only was he threatening me but our unborn child. He also tried to break into my house a couple days after he threatened me. Before all this threatening and him trying to break in...I tried talking to him and getting him to stay away, but it didn't work. Finally after he tried to break in...I had enough of it and I had to go to the cops. I told my ex I went to the cops and if he came to my house again he would be arrested on criminal trespassing. Finally he got the hint!!! He ended up moving up to wy so I haven't heard from him or seen him in about a year and a half. Now everything is great. My daughter is now 8 months old. I'm dating a new guy...And we are engaged. He loves me and my daughter. He treats my daughter as his own. I'm not sure exactly what your situation is...Or if he was as bad to you as my ex was to me. If he was as bad to you as mine was to me...Then I completely support your decision in not wanting to tell him that you are pregnant. However, if it was just minor problems yall had, he should know that you are pregnant. You just need to think of what is best for you and your unborn child. And just remember that one day you will have to explain to your child why daddy is not around. It might come back to bite you in the ass if you have to tell your child that daddy isn't around because mommy didn't tell him she was pregnant! I'm still having hard time thinking of what I will have to tell my daughter one day. I mean...I know in my heart I did the right think, and that my daughter and I are better off without my ex. But it'll still be hard to tell my daughter why things didn't work out. Best of luck to you. And sorry this is a late reply to your post!
