Hi L.. Congratulations on being such a WONDERFUL WOMAN!!!! Raising a bi-polar child and assisting and ailing EX, you are my shero!!!!!
I think it's time to tell the BF about your daughter. If he's been with you for five months, he knows your character and that you have done the best that you can in raising your child. We can direct our children, but ultimately they make the decisions on how they will live their lives. As you stated, you will support her and the baby and you should. You know how difficult it is to be a parent, regardless of the age you are when you give birth.
Since you and BF have only been together five months, I don't think he should be too upset that you didn't introduce him to your daughter. 1) She just lost her father who has been sick for a while, so this an emotional time for her. 2) She needed to deal with the loss of her dad before she realizes that Mommy has someone in her life. 3) You wanted to see where it was going. I dont want to put my views on you, but I wouldn't want to introduce my children to every man that I met. Only if i saw there was a possibility that he may be around for awhile.
L., I hope all works out for you and BF. And that the new baby is healthy and your daughter is able to be the best mother she can be.
Have a happy holiday and a blessed new year.
