Well, I gotta hand it to you for being honest. Your feelings are very very common on these boards - stepdad thinks a small child is too clingy and basically only wanted to marry the woman, and not the kid. The stepdad usually goes on and on about how the kid is abnormal.
You're honest, though - your wife doesn't have enough attention to go around, and you want to be getting it, not him. Your wife must feel incredibly pulled in both directions - and if she's a good mom, it's you she'll let go of instead of her child.
Unless, of course, she's now pregnant and not free to leave.
Children are born with the strong desire to keep their "nests" intact - and this child perceives you as a danger to his place in the nest - which I think you'll agree, you are.
Go a week without ever saying "go away", "let go of her", and see if he doesn't ease up a bit. At least your wife would get some relief from the tension.
My younger son is probably what you would describe as 'clingy' at 11! :>) But my husband has no problem with it because he is not in competition with him. He loves him as much as I do. If anything, he's jealous of our son preferring me all the time. It's hard when you are the step parent. I totally get it. But kids are all different and the boy loves his mama. And he might be a little extra clingy as a new man is in his mother's life. This is natural for a child. Think of how you feel . . . you call the child jealous but deep down, he's bugging you because he too is competing for her attention. It bugs YOU . .. imagine if you had the emotions of a 6 year old and the immature ways a 6 year old has of communicating it. So, many kids in a step situation might be a bit more clingy. Personally, I think the best thing to do is to ignore it and allow him to cling as much as he wants. He'll begin to separate especially as he feels more secure in the situation. Good luck.
Well, yes, it is normal for a kid to go through a phase every now and then (and the phases can be long!) where he really needs to be in emotional touch with his parent. You married her knowing she had kids, but I am guessing you never expected they would have needs that automatically come before your needs. But they are only kids once, and actually the time is shorter than you think right now that they will be kids in your life or your face or "up her butt." If a parent wants a child to grow up without trauma and emotional wounds and sadness, it matters to reassure and cuddle the kid, whenever the kid needs it, no matter if the adult judges the kid's needs to be silly. (In other words, if a kid needs, he needs.) And this matters now because this is the only shot she (and you) get to help this child through this part of growing up. You don't want me to say it probably, but it matters even more than it matters that you, an adult, get whatever you want from your wife at the exact time you want it. This is because it is laying the foundation for the rest of the kid's life, and your foundation is already in place and won't be derailed by a few years of her having divided attention. I'm sorry this is happening, usually when it is not a stepdad but a biological dad, the dad doesn't protest this point because he loves the child as much as the mom does and wants the child to come out of his or her childhood without emotional gaps. Harder for a stepparent to develop that mindset. But I will say, if you can develop that mindset, that a child with needs should have his needs met, your wife will value and appreciate you more than rubies, and it will cement your marriage forever.
