I made a girl pregnant (by accident) and she ended up having the baby. I made it clear from the moment she told me that I did not want the child and I feel no connection to the child, therefore have not felt the urge to tell my parents, however she is insisting that i tell them or she will come to my door and tell them herself.
What can i do? Does she have the right to come to my house and tell them?
Unless there is a restraining order, there is no legal reason why she would not be allowed to contact any person and inform them that you are the father of her child.
What you can do: you do not have to have a relationship (visitation/parenting time) with your child. However, if Mom gets your paternity established, legally, then she can also get a court order for child support. And what you can do is pay court ordered child support.
Note: if you refuse to show up at court, or blow off getting a court ordered DNA test, you can be found, legally, to be the father by default.
Perhaps she will eventually meet a nice, loving man who marries her and wants to adopt the child. Then you would no longer be the legal father. However, not all stepfathers choose to do that (for a variety of reasons).
That is a fair point. Without sounding selfish or rude, but I just don't want this situation to ruin my life...I mean I told her my thoughts and have made them quite clear however she seems to be still trying to enforce that my parents knowing about the child will affect my decision on partaking in the child's life. I've told her my thoughts and I won't be involved so I don't see why it's so important for her that my parents know. Thoughts?
You've told her your thoughts: that you don't want a relationship with her or the child. Fine. Therefore, it's really none of your business what she does. That includes introducing herself to your parents and telling them that they have a grandchild.
Now, I suspect that your concern is that your parents might react negatively to you having fathered a child. Or perhaps it is that you fathered a child with someone that they would not approve of. Perhaps you would prefer that your parents think of you as a "nice" guy, who doesn't "accidentally" have sex with people.
I suspect, having known you for your entire life, that they have some idea of what you are capable of.
