Is this appropriate or am I just being too ...

While it may have been more appropriate to include a picture of you and your daughter from the son's wedding, it's possible there was no better picture. It's not really an excuse, but it does give some validity to the original picture chosen. I think you're reading more into this than you have to. Just enjoy your newlywed life and don't stress about the small stuff.

I think you need to let it go...you can't force a family, especially when the children are grown and on their own!  Maybe you should make your own photo album of your life with your husband, and represent it the way you would like it to be expressed?  I don't think your step son was trying to slight you; I just think he gave his father a gift he thought he would like.  You didn't give some specific details that I think might be important, like your age, the son's age, how close all of you are normally, etc.--if we're talking about everyone being adults, and you and your husband getting together after he moved out on his own, it is possible that he just does not grasp the concept of you being part of his family?  Not in a mean way, just in a kind of "out of sight, out of mind" kind of way?  Regardless, I really do not feel this is worth getting upset over; cherish the love you have with your husband--the relationship and the commitment you have is with him and not his grown son!!

His past is a part of him, but it would have been nice if you were also included in this album. Sadly, the Son probably doesn't see you as a big part of Dad's life at this point, since you've only been married 2 months.  I know how it feels to be left out and it's not a good feeling. Not all people are sensitive to others, nor do they think things through when planning an event such as this. A similar situation happened in my family; My Uncle has remarried and we did a slide show...most was of his "new" family, but there were some old pics of the former Aunt, since she is the Mother of the grown kids.  In your case, your step son should have definately put some type of photo of you in that album.....There is no excuse for it just because you are not his Mother and this leaves a bad taste in your mouth when starting a new life with someone...Best Wishes.

It was a gift to his father you are not sensitive but insensitive. If there is more room then your husband can put one of you in it.

Let it go. It rightfully hurts your feelings but the marriage is new and you will go on to make memories with your husband to be added to the album. If this is a first insult i would truely concider it a mistake. If there have been other issues it should be your husbands place to address them.  But don't tear yourself up over this. Don't sweat the small stuff.
