Plus, we haven't even told him about the event
Wait, you haven't told HIM about the event? Back up. Your HUSBAND needs to talk to him about it, to let him know about the event, and open the door to finding out IF he wants to go.
I think in other cases, like if you want to take him on vacation, then it's possibly best to talk to his mom first, but in this case it's about his future half-sibling (a very weird relationship if ever there's a weird relationship, IMO, and I"m a person with two EX stepsisters and stepsibs who are also my step second cousins...talk about weird relationships~!), and he should be involved in this process.
Was I the only person who sensed a bit of sarcasm in Rock'n Robin's post?
I don't know... it's hard not to be selfish sometimes... I mean honestly, don't be offended please... but if I were his mother... you would not be my sons family... in my mind... Now that is me, she could think differently... but I am who I am... and my DD is my daughter... as a mom (and you will learn this soon) it is difficult to imagine another woman in your childs life and the cosmos forbid they ever tried to discipline her... it would be a bad day
That's awfully sad. I can remember weekends at my dad and stepmom's house where I might have acted up a bit. Now my stepmom is almost too easy going, but if she weren't that relaxed and if my dad were at work at that time, it would have been absolutely appropriate for her to discipline me.
Though I do admire her restraint (though over the years (coming up on 30) we've grown apart due to some philosophies that differ between us), b/c I'm a HUGE fan of It's A Small World and my dad bought me the album. I listened to it over and over and over for a weekend, just groovin' to the music (seriously), and amazingly, she did NOT kill me. I think she mentioned it when I was around 28, how close I came to throttling, LOL, and we had a big laugh over it (and I apologized, but I still do love that music).
Honestly, it is not her job to plan 4 months ahead to make things easier for her EX husbands new wife.
You know, I read the OP a few times, and in that first post I didn't totally get the impression that it was the OP in contact with the mom. I came away just not knowing who is talking to the mom, so I didn't want to make the assumption.
If the OP is the one talking, IMO, stop. Let hubby work it out.
But as for making it easier for her ex's new wife...even though they haven't told the boy, it's about him and his new half sib (sorry, I just can't refer to a baby by sex until after baby is born, just doesn't sit well with me, which is why I'm saying "sib" and "sibling"), in a way.
But ultimately, it just might not be a big deal to him.
Kids vary so drastically, and so do parents. My dad and stepmom took forEVER to tell us that they were expecting M1 (they had two boys, both M names like mine, 2 years apart). Then it took at least a month if not more to meet him, and I am fairly sure it was 2 months before we met M2. And we only lived half an hour away from them!
It was 3 months when I met C, my half-sister who is 25 years younger than me (I'm 13 and 15 years older than the boys) (but that was mainly b/c I was in chiropractic school and very poor, and had to find the money to get there), and my brother had already divorced them by that time and only saw C at my wedding, but didn't introduce himself to her (she was my junior b'maid, so you can see how different two people can feel about half-sibs) b/c he simply has no interest in them.
My dad and stepmom tend to not think I want to be a part of things, and so I don't get invited to graduations or parties or anything; I have to invite myself. So you can also see that *parents* are different too.
To the person who said they would be difficult...one of the things I loved most dearly about my mother is that she never once was difficult with my father, even though he was (is) VERY difficult. He was late to pick us up most of the time, he wouldn't show at all some of the time, and she would help us mend our broken hearts without ever saying anything against him, though I think she did let us know that it's just who he was, and not anything about US.
I'm sure the OP's husband isn't like my dad, but in our case, we figured out who our dad was over the years, and that was far more valuable than any rantings or difficulty my mom might have said or created.
Of course, I don't know how I would have the restraint, but I hope I would, b/c it was such a graceful way to be.
And *like* the OP, my stepmom had nothing to do with the breakup of my parents' marriage...she was like 18 at the time of the divorce, LOL (10 years younger than my mom). Other women helped to break it up, but my mom was always civil with them too, and we actually spent visitation weekends at the main woman's house...don't know how my mom did it, but she did, and thanks to those visits my brother and I can whistle without looking like we're whistling (the woman's son a bit older than me taught us), LOL.
OP, I think it's time to include your stepson in this event. I'd have your husband schedule a time to talk to his son and son's mom together (without you please), to hash it out.
