S., I have not had this happen to me personally, BUT....my 16 year old daughter has....I call her my daughter, because I have been with her longer and been essentially her mother since she was 6. Her bio mother(and this is very hard for me to comprehend....Because I have 2 boys since me and my husband got maried, and like you, I would give or do anything for them.......but her bio mom just up and left, she took her for about 6 months, and then when she didn't get along with "mom's" boyfriend, my husband was called and told he had to take her...so he flew her home and we have had her ever since, with bio only seeing her 2 times since then. I do not understand how a MOTHER can do it....I have seen it alot with guys...but moms....that just blows me away.
I didn't mean to tell you so much about me, but that was just to let you know, I do have a clue of where you are coming from...I would suggest, even though it sounds as though you have a great support system....there is nothing like friends....I found MOPs..Mother's of Preschooler group....it is so supportive and just a great "time out" and relaxing "me and my girlfriends" time....there is a brand new one starting at Mannassas Baptist this fall. You can emial me directly if you want more info, or you can also go to www.MOPs.org if you do not live clse to VA...they have them across the US.
Also, if you get into a church that you can feel really comfortable in, you can find some great Dads out there that will be like a "father figure"..mentor type person, not talking about a personal relationship between you adn a man there, just other married dads who teach in a class he would be in, or a VBS during the summer. Things like that. He can still have a "father figure" in his life to look at for a role model.
I wish and pray you continue to be strong and find where you need to be to get what you and oyur son need in your lives
