I'm new here and I'd love some input and advice from stepmoms.

I have two kids. My son, who's a tween, is from a previous relationship. Fast forward ten years...I got married recently and have a young daughter with my (awesome) husband.

I am BLESSED to have a great relationship with my son's dad. We never went to court, worked out money/time/parenting on our own. We're friends. My husband is 100% supportive of this relationship - we've all gone on family stuff together, the whole nine. It's wonderful, and great for my son.

I guess I should say, though, that we have worked HARD to make it good. We have totally different parenting styles and disagree often, and work HARD to keep it respectful and healthy.

My son's father also has another kid, who's 6, with a woman who he's no longer with (let's call her Mom2). Although her and I get along fine, she makes his life very difficult....basically is just angry their relationship ended, and years later won't stop throwing a wrench in things at every opportunity. (Mom2's not a direct part of the situation I'm looking for advice on...but her behavior is relevant.)

My son's father just got married. To a woman I thought was wonderful. Went out to dinner with her, just me and her, before the wedding to really get to know one another...seemed totally on board with helping to maintain the healthy relationship we have. I was so happy to have her in my son's life. I helped with the wedding. I thought it was going to be awesome. My husband was outwardly happy, but had his doubts....nothing he could put his finger on, but just felt something wasn't right.

Fast forward a few months, and the relationship with my son's father has totally changed. He's just sort of stepped to the sidelines and let her handle parenting conversations with me. (They have one phone. It's impossible to just get ahold of him, and I feel icky about trying to circumvent her anyways.) He acts if nothing has changed.

Communication has slowed to a trickle. Last week, they sent back a parent teacher conference form without even talking to me about the date/time. (We ALWAYS go to EVERY conference together.) I have to work on the night they scheduled the conference, and am now calling the school to try to make other arrangements. There were no apologies for not calling, no explanation. I get this vague sense of hostility from her every time I talk to her. (My son says things are fine at home - apparently it's just her interaction with me and/or my husband.)

I am totally at a loss. I want so badly to maintain the good thing we had going before she came into their home. I want to address this in a respectful way, without saying, "things were better before you got married to my son's dad."

She doesn't have any kids, and this is her first time as a stepmom. I wonder if the hostility from Mom2 has anything to do with it...? I don't know how it feels to come into a situation like this, and I'm at a loss about the weird hostility vibe.

I feel like I did everything I would want someone to do for me if I was becoming a new stepmom. I helped with their WEDDING. I told her over and over how happy I was that she would be the kids' stepmom. Everything was great. Then they're married, and now....huh?

I called a "family meeting" tomorrow. I am going to bring up the parent teacher conference (and other recent events like it) and explain how this made me feel, and try to figure out ways we can work better with each other.

But I'm nervous...any input or advice? Especially from stepmoms? The last thing I want to do is make things worse. THANK YOU!!
