She's back

Well my sons birthmom is back in town. She was back East in jail. Got out, moved closer, which was still a bit close. Then I learned she moved again back into our area. A bit too close in some respects. I haven't had to deal with this through the whole process the bio dad was in jail popped into the picture for a total of one phone call to the adoption worker and dropped into the abyss again. The bio mom, well not much from her except the one letter and heck it was nice enough. What happens when she asks to see him? Or 'happens' to go by her fathers house (we allow him and our son to have visits). This kid is FINALLY gatting over, more finally coping with the trauma of losing his last foster adopt family.
I will sit back and wait to see what she does for now. I gauge my next step. She still has her daughter with her which is a positive. I may get to the point where I will meet her for coffee or soething one day. I have a positive relationship with my foster sons mother. I hope I can eventually have the same with her right? Eventually
