Step Families Support Group
Traditionally, a stepfamily is the family one acquires when a parent enters a new marriage, whether the parent was widowed or divorced. This community is focused on many of the relationships and issues that may arise within stepfamilies where you may find answers from some members and you may help other members with their questions.

If you are not for sure about being a full time stepmom, I would suggest that you wait longer until you are sure. I do understand wanting to escape to your own space.
Hope to get to know you better
I always feel like I need to do something to "fix" this, but it's hard when my husband doesn't back me up. I am trying to look the other way & focus on my own daughter (who's almost 2). At least I know she will be brought up properly.
And as a side note, I agree with krsnow36...make sure you're ready to take this on full-time! I sometimes wonder what my life could have been like if I had run screaming instead of "saving" my husband from the life he had before me. (But then I remind myself how much I do love him, our daughter & our life together.)
