His ex-girlfriend cheated, but says he is her baby's father.

And now she's dating his sister?

My son, who's 18, has found out that one of his ex-girlfriends is eight months pregnant.

He knows nothing of the sort of her being pregnant until now, and he's just expected to accept everything with no questions asked.

My daughter, who's 20, is good friends with this girl and knew about her pregnancy,

but said nothing to us because her friend asked her not to.

My son was head over heels for this lady, but she ended up breaking his heart by cheating on him

and was very needy and manipulative.

He spent a lot of money on her because she'd ask for gifts that my son couldn't even afford,

and she'd convince him to use one of my credit cards to achieve them.

My daughter, who isn't currently living with us and is actually rooming with this girl by her college,

is also being manipulated by her,

and thinks she only does good, and doesn't believe that she convinced her brother to use my credit

card, or that she even cheated. She showed up with my son's ex-girlfriend at my door to

help her tell us that she's pregnant. When I saw her there, at my door, visually pregnant,

I knew she was going to be saying that my son was the father of her child, and I immediately said that my son will not be putting in any money or time until there's a paternity test proving that it is his child. My son actually backed me up and agreed. My daughter was horrified by my comment and accused me of

encouraging him to be a deadbeat father and was upset that I didn't even give them a chance to

explain themselves. My son's ex started crying, saying that you always assume the worst of me,

and that she went eight months of pregnancy alone, and the least we could do is ensure that she's taken care of

for the betterment of his child. I do agree that if this is his child, we're going to ensure that

she's doing well to ensure baby is doing well. But I don't want my son to be involved with her

only to get his heartbroken again and only to find out that the child isn't his. Am I the jerk here? As a quick update.
