My wife post pics on facebook of her and her ex's kids. She always tags him in the pics. He is not in the pic. I'm not tagged and I just wonder if it's ok for me to feel jealous, hurt, upset?

Facebook stuff means nothing to me. You could talk some to her about it but it doesn't sound that bad to me. I think Facebook causes more problems and misunderstandings than anywhere else. Just casually bring it up in a conversation and let her give you her side. I wouldn't be upset in the least ! Kind of trivial, don't you think?

Oh my....one of the reasons I'll never join Facebook or anything like it. Someone posts a picture with no ill intent and it just blows up. Those are her children! Regardless of who their father is, she's proud of them! It's just a website!

You weren't in the picture so there is no reason to tag you. If she were to tag you - people would be looking for YOU in the picture. Let it go. She tagged the ex in case he wanted to share the pix with HIS friends. Surely you have better things to worry about than Facebook.

You choose to join into their existing relationship ... So you should have known what you were getting into.  It's pointless for you to have any hard feelings, at this point - unless you want to divorce her.

What you are feeling is quite normal under the circumstances but the big question here is why is she doing this?  To get back at her ex, or you or is she simply that proud of her kids that she really doesn't care whose feelings she steps on?  Now if she posts them with her EX, then maybe Id start to really worry but let it go for now and move on. You didn't say if youre having problems within your Marriage or why she divorced her  first husband ?  Maybe shes some kind of attention seeking person here

I stopped using Facebook because everyone is in each other's business. You can feel hurt because you cantncontrol emotions.. Keep in mind that those are her kids and his kids too. That's most likely why he's being tagged even when he's not in the picture. It's normal..

Sure it's Ok to feel jealous, hurt, upset---as well as angry, confused, and whatever else you're feeling.

Feelings are reactions---they are responses to stimuli and difficult to prevent. 

There's no detailed roadmap to having a successful blended family---you all have to become "pathfinders."

I don't know if you wife knows how what she is doing on facebook affects you.  And even if you tell her, she had a relationship with that man and they had children together.  No matter how significant an influence you now are in their lives, his existence as their father is something that she can't simply ignore; and I'm sure she is still in the process of getting comfortable with that reality and learning how to handle it.

You could use some help dealing with this.  Counseling for you to clarify exactly what and why you are feeling what you are feeling because of this situation would be very useful.  Then depending on what you and the counselor agree would be the best approach to bringing your wife into a solution that works for both of you, you can go forward from here.

Consider the counselor as a "local guide" to assist you in your "pathfinding."

Best of luck---this is eminently amenable to a workable solution.

I mean, sure, it's normal to feel that way but you shouldn't let it get to you. It's a website.
