Si I have a 5 yr old step son,that my SO of 4 yrs had in his party days with this girl that ended up lying to him but telling him that the little boy wasn’t his son because she was still with her boyfriend when the messed around,we’ll fast forward 2 yrs and he’s now living with me and my Daughter that he has loved since before she was even born,I was 7 months pregnant when we started hanging out..we’ll she found out he had a daughter and decided to call him up and tell him to go get a paternity test done because she doesn’t know who the dad is and didn’t want to ruin her relationship if her guy was the father..we’ll he didn’t go because he didn’t want to have problems or worry me if the child wasn’t his,turned out the guy wasn’t the father and my SO supposedly is the father. There hasn’t been a test done on his side because he is taking her word on it but we never saw any paperwork of the other guys test results. Well fast forward to now it’s been almost 3 yrs of knowing him and having him in our home with us whenever the mom allows us to have him,and there’s just something that always bugs me about him. I can’t stand hearing his mothers name or hearing her voice,I hate how she did things with my SO and practically skewed him out of a normal relationship with his son,and it bugs me so much,how she’s call during the day when he’s at work,and his son isn’t even with him,because I watch him when dads at work. I don’t know why I can’t stand him,and I’ve thought of many reasons but it all goes back to how he’s not always around us. He’s almost 6 yrs old and he’s super behind in  very way,speech is just awful,he can’t do things a child his age should have no problem doing,he doesn’t know how to brush his teeth,he couldn’t dress himself intill I got him to try to do it himself,he seems way of on his education level. And it all goes back to how he’s raised with his mother! I don’t know if it that because my daughter that’s 4 does a lot more by herself than he does and my 2 yr old is learning faster than him,and it might be I’m just not used to having to do everything for a child who could do it by themselves. I don’t hate him,but I can’t make myself feel lovable twords him. I don’t hit him,yell at him,punish him,because I don’t feel like that’s for me to do, it at the same time I can’t treat him differently than my other 2 kids. I don’t know could I just be a bad person?
