I'm pretty sure you are entitled to 1/2 the appreciation of his pension over the time you were married. I expect he's thinking "if I give her $70K for the house, she'll be happy with that and not push for the pension." I think he has a rude awakening coming when he finds out just how much he's going to owe you in equitable distribution.
Definitively see a lawyer.
