Something fishy is going on here and I want to know what it is!
This is what I find odd. He signed his rights away and the girls have taken their stepdad's last name. I have no idea why he would do that since he's still in their lives. Plus, he pays child support. The cs itself doesn't bother me and if it were voluntary, I would understand, but it's court ordered. Something doesn't add up.
I've tried to discuss it with him, but hr refuses to talk about it. If things weren't getting serious, I would say it's none of my business, but if we have a future together, including kids of our own, I think I should know what's up with the kids he already has.
