I'm sure people are tired of hearing my story from other posts! But it's relevant to your question, so here goes....My guy has been living with me and my kids for over two years, it's been nearly 4 years since I left my husband. Said kids are 17, 15, 13, youngest being the only girl....I've known my guy for almost 30 years, he is 10 yrs older than me, I babysat his daughter when I was a teenager....Even though we are officially divorced now (with the ENORMOUS legal bills to show for it), I don't really see the need to get remarried, he would like to, he is patient on that subject. Bio-dad is legally in the pix but takes very little REAL interest in the kids. Technically they are suposed to spend every other weekend with him but they are busy and he won't take them if they have plans....bio-dad and I have a very strained relationship still, I left him because he's an abusive drunk, he thinks I left him because I decided I don't like him anymore, sigh, he will be mad at me for the rest of his life, he lumps the kids and I together as a single unit, when we were together he behaved like the kids were a hobby of mine that he would allow unless it got too expensive (which it always did, of course). Still he treasures his bragging/bitching rights without acknowledging the responsibility that goes along with them. The kids and I have a pretty good thing. They are all excellent students, we have a very relaxed household. My guy for the most part eased easily into it. Besides being my financial savior, very generous with what's his, he is much more of a father than their father is. He is the man with whom my daughter (13) has a 'daddy's little girl' relationship. He offer my boys 'dumb guy' stuff they never got from their father. He clearly loves the kids and enjoys their company, and vice versa, but they will always call him by his first name. Sometimes we do use the term step, but it almost lends a negative tone that is not appropriate for us. It's not a perfect situation. Occasionally my guy is frustrated, he wants to 'parent', sometimes he would like to try to do a thing different than the way we already do it, I don't want him to feel he has NO SAY whatsoever, but I feel like things are working, why change it? It makes me feel unappreciative of his contributions when I don't change a certain parenting style on his suggestion. My kids warmly embraced him because HE warmly embraces them, but we do not need any parenting advice, you know? Anyway, I definatley feel for the sake of my relationship with my guy it would've been better to wait a few years before co-habitating, I am so into my kids, I am often not as supportive to him as I should be. Overall though, as far as blended families go, ours is better than most, but not perfect, and will continue to be a work in progress for the next 5 years and beyond. It takes CONSTANT communication, on EVERYONE's part, everyone needs to feel free to respectfully say what's on their minds, everyone ELSE needs to LISTEN and THINK before responding....we TALK everything to death, we talk about things to the point where we're all on the floor laughing about how silly we are! If you peel away the layers of our own behaviors, in the core you always find love............good luck to you! Sorry it's so VERY long! Two more things I feel has aided in our success, first my guy is an old family friend, my family and I are all very close, it helps that they already know him.....also he is a field engineer and travels frequently, the kids and I have time for it to be just the kids and I, plus we actually get to MISS him and are glad to see him when he gets home! Hope this helps! But wait! there's more! We are a faithful family. Without sounding too preachy, I'd like to say believing I have help from God, and especially Mary, instills a sense of peace I might not have otherwise. This is another thing I share with my guy that I did not share with my husband, he did not believe in God, went through all the motions when asked to do so but will honestly admit that he is not a believer, which to me is sad, but I can't change him.
