Am I a horrible person? I need help. Drama left and right.

Tanya

So to fill everyone in. I have 2 kids, they both have different dads. My oldest daughters dad I was with for 4 years. A month after we broke up I hooked up with my youngest daughters dad 1 time and I got pregnant. Haven't been in a relationship since I left my oldest daughters father.

Now I'm kind of seeing this guy and heres the plot twist, he and this girl who's pregnant with his kid havent been happy in a long time. He hates her but wont just ditch her with a kid (which I agree with) and that girl is my ex's sister. We never liked or got along with eachother. Hes moved on but she wont let go. We talked about our feelings with eachother and we both have mutual feelings.

She moved out of town and he stayed behind. He currently lives with me. Hes a very jealous person. Another plot twist. His brother is my youngest daughters father. So this whole situation is fucked up in so many ways. (More than what I mentioned but its not my business to tell anyone anything else) I feel like a POS about it all. I just want someone elses opinion on this situation. What is everyones thoughts? Am I a horrible person for being happy and possibly in love with this guy?
