First ----- Whatever stated in notice remeber they are not your wife creation , it is Lawyer creation may be under influence of some other third , fourth person. Even in suit if any thing writtemn whatever stated remeber it is not your wife who stated but some lawyer . So have soft corner for your wife.
Second ---- Regarding future you talk with your wife in person and decide what should be done about future. Here talk as friend not as husband and wife. In life you are not alone even women become disable after marriage due to some Neurological disease or accident .
Third --- What you studied , since you can type I wanted some help in typing and computer related work , Myself too learning some new things like Making Mobile APP , Law and in touch with person who was my school friend to do Software related thing or make APP , He has company so you may join in learning new skills .
Starting life again is also spirit in itself.
