I can see how you feel. I think you should test the other person first if possible. It's best to find out without letting your partner know if there's a way. If you think the other person will tell your current partner then i would just be honest with your partner. It is not fair for him and he has the right to choose. I know by doing this, he might leave you but I don't think i can ever keep this a secret. You made a mistake but it's okay to be honest and this way you will know whether he loves you or not.
I disagree with you! I can see how your thinking is from reading this and the single mother forum you posted.
Is it possible to test with the other person? That would be the first thing to do.
Do you still have a copy of your first ultrasound when pregnant? If you do, it might be possible to figure out the question of paternity from the dates on it. Would need to know how early in the pregnancy it was (how many weeks pregnant they said you were) and what due date you were given at that first ultrasound. From that it might be possible to figure out the conception date, if the ultrasound was early in the pregnancy. Would also need the dates of sex with the other guy.
If you and your bf went through a separation around the time of you conceiving, he will likely understand the possibility, especially if he knows you were with someone else. If he doesn't know, it'd probably be better for your conscience if you came clean. I know for me that if my husband cheated on me, I'd want to know and I'd have the right to know. That said, just because you make a mistake, doesn't mean you are an awful, terrible person. We are human. We make mistakes. If he loves you, it may take time, but hopefully he'll be able to move past it.
I agree with the last 2 posts, if thats not his child he deserves to know the truth, plus u never know what destiny has prepared for you god forbid that one day your child might need some type of medical emergency and truth comes out its not his and then it will be worse for both baby and him. But i also think the smart way to go about it is test the other person and if he turns out to be negative then just keep it to yourself.
Test the other person first, if they are the bio dad tell your boyfriend. If they are not, take that mess to the grave. Good luck.
You can't just not tell him. He has the right to choose to raise another mans baby or not! He may be mad but you could move forward. It's not fair to your son or to your boyfriend to lie to them all of his growing years. There is nothing wrong with getting DNA test these days. You not telling him is really all about you being scared not the best interest of your boyfriend or your son who is still so young won't remember. If there is another possibility the other man deserves to know as well. Every man deserves the right to know the truth and to raise there own child.
If he accepts the child as his own why ruin that? I would just leave it alone and just move on. One mistake doesn't mean you and the child should suffer if he decides to leave because the baby isn't his. If he loves that child and cares for that child then blood or not he is the dad.
