If you haven't told him directly in an assertive voice that you want this to be a weekend just for you and your family without his daughter then do that now. Be diplomatic and kind, but let him know that including his daughter is not what you want for your birthday.
I understand him not wanting to include your friends if they do not have husbands to also come. He would be the only male and it would be an awkward situation.
LATER: I don't get it! In June you didn't have enough money to pay your step-daughter's air fare so that she could visit this summer and now you have enough money to take the whole family on a cruise?
In a previous post you complained about the drama of flying his step-daughter to your town because her mother doesn't make plans, etc. You say it isn't fair to his step-daughter to have to pay for the drama but yet here is more drama involving her and it's drama created by you this time.
Your husband's daughter should be high on your family's priority list and it should not matter that her mother is a flake. You were right. It is not his daughter's fault but you are continuing to let the drama surrounding her visit with you to continue.
Yes, it's your 40th birthday but when I read your post from June of this year I don't understand what is going on. In June you didn't have enough money to fly his daughter to spend time with your family.
I reread this post and can see the drama in it. You keep changing your mind, talking with friends and including them in your plans, and now you're upset with your husband because you said OK when he added another idea to your plans. Sounds like his change is just one more change and you said OK to it.
Mommy R. suggested that you tell your husband you've already invited your friends (you have haven't you? Your post sounds like it.) and that he can invite his daughter. Be respectful with your final decision and let the drama go.
I hesitate to say this because I'm not your friend and am not able to word this gently but it's important to bring this on the table. You are a part of the drama. You can stop the drama by deciding what you want and being upfront about it.
By the way, just from reading the posts, I think that you are doing the same thing that you accuse Lisa of doing: causing drama by not making plans up front. Perhaps that is why Lisa's way of doing trips is upsetting to you. You can see yourself in the way she plans and don't like it. Unconsciously you don't like it in yourself, either. You don't like it so much that you aren't allowing yourself to be aware.
You're a good person. You're not perfect and that is very much OK. Once we accept our own shadow we can accept the way other people act too. You are OK. So is your husband, Lisa, and Ella. (Ella is the daughter and Lisa is her mother.) Find the love in your heart for all of you and working this out will be much easier.
I understand you wanting to make this a big deal and all about you. At the same time, I don't understand. I don't remember my 40th birthday. I remember feeling sad because that meant I was "over the hill." Facing 40, I began assessing my life thus far to see what I had wanted to do with my life and what was still possible in the time I had left. I am an introspective person and perhaps you're not. Or, is it possible that the big hoopla is about not facing other issues in your life at this mid-life time?
