Hhmm if her friend suggested this i wonder for what reason.You say "you believe her for the most part",so something is still not right in your thoughts about it.If she is unsure how you feel about her and needs to pull a stunt like this i would be very concerned.I know its your decision but dont stay around just because you have a child with her.If the love is not mutual its a no win situation for either of you nor the child.
