Update...Meeting time.
My DH went to see a lawyer that he was directed to him from his dad. "Family Friend" lawyer...who knew.
So the lawyer instructed him to go see them and not talk money or paternity. Just do a meet and greet, keep it light.
My dh was happy to talk to a male neutral party for once.
The meeting was set up at mom's apartment.
However, the mom requested that she meet with him for 10 minutes beforehand at this bar near her place, ended up being 20 mins. (think where everybody knew her name)
So he did. It appears that the "mom" is really "off" as far as coming to terms with her own past going back to her own father, let alone this situation. She is not happy her dd is doing this. However keep in mind that when she started divorce proceedings the 3 kids went to live with the dad. The mom is not closely bonded with her dd.
She is also a "manipulator". However DH and I know how to handle people like that, so it is just annoying & sad from our perspective.
The daughter from DH's perspective handles the manipulation as well as a 21yodd can...They bicker back and forth openly.
Anyway, my DH would prefer to leave mom out of this and will push it in that direction from now on. He met with her as expected but now there is really nothing else to say to her.
OK, so they go back to mom's place and meet. The daughter is crying out of happiness and scared at the same time. She brought her 2 kids with her. (hehehe....grandpa

.....sorry we find that funny....oh, so much ammo for all of us soon.

)
Sorry, had to express that.
DH believes she is genuine in her pursuit. She wants a relationship with him and more...So he has explained that he (and probably me) will get to know her over the next 4 months and then when summer gets here we will all decide how we want to go forth.
It is a good plan and I hope it can go that way. If this is to be long term and an addition to our family I want to go slowly and do it right.
If she is dh's dd for sure it won't matter we wait until summer to bring everyone up to speed.
DH will do a paternity test under the guidance of our lawyer.
So.... so far, so good. My hope is that it keeps going good.
