no, annoying would be if she complained about unreasonable things, but that's fine you can talk that out or get used to it, cause in a healthy relationship, being annoying is normal and fine and shows that you're human, like the rest of us. but her... her, no she's not annoying, she's showing cases of some extreme form of mental manipulation and some other form of mental illness that was triggered from pregnancy. but yes she needs help and the husband needs to divorce her and move out with his daughter or try and work things out (cause it might be a mental illness and not her entirely; if that's her true nature then divorce her entirely cause she's is messing up not just husband, but also her daughter)

its his dad

the mom got the artificial insemination, so no dad is in the picture. she's most likely talking about the previous owner of the MC's body

wait, when did he show his unique skill?

so essentially like Naruto's shadow clones, where when they disappear, the memories and experience are transferred to the main body

Anyone that can't take rejection well and do shit like that deserves whatever bad karma is coming to them, her and her parents. I mean, he didn't even mock or belittle your confession. He even went as far as knocking himself, slightly, based on his and his family's financial situation, and yet, your 10-out-10 mental gymnastics got you making it seem like he flat-out rejected you for no reason or even straight-up humiliating you. Out of all the bs you could have done, this was one of the lowest. 

wow, if that was your take from all of this then I really suggest you stop reading. don't cause yourself unnecessary stress
