I wouldn't be thrilled by this, but it is what it is. Courts don't like to take custody away from a parent (especially a mom) unless there are some major problems. The child is only 3, so I doubt she is learning that it is "ok" to do what her mom is doing right now, and it really means that you and your boyfriend need to work that much harder to show her what is right. Which in turn I think can strain your relationship. You and he have a responsibility to work out whatever issues may come your way since you are in her life as well. Tough times I know and I'd feel the same as you do, but I just don't think it's in the best interest of the child to take her from her mother. But we must not know the whole story if you guys are seriously considering trying to obtain full custody. Hugs to you, because I know this is a challenge!!
Oh! And I started dating my husband in July 2002, ended up pregnant in September 2002. Not planned obviously, but it is what it is. We now have 3 amazing children and have been married for 6 years. Tough times? Sure, but so does everyone. So maybe she is going to settle down now?
