only 6months is required in texas to be able to file,... as far as alimony,.. not unless your unemployed and or uneducated its very rare (especially if your under 10 years)... your under the 10 year rule as far as his retirement so thats not going to help you (if he has any)..... if you have two vehicles most likely he will have to give you one... if one is paid off, you can fight for it(for the kids sake)... even if it's in his name... its a 50/50 state... if you file you can have him removed in about 14 days and stay in the house,(thats what I was told)... and if he is bringing in his pothead friends, yes you and the children are in danger(if the cops were to be called to your house they take the whole family in, children go to foster care, and you go to jail along with him)... in my opinion, you could turn him in, have him arrested for his drug use and then he has one strike against him(but dont do it at your house)but the you get nothing if he's in jail.... (if it were me) I would use the money your getting from your sister and file for divorce if that is your decision... forget about the car, protect your children and yourself.... you can have him pay your bills while the divorce is pending... that will allow you time to get on your feet and get a car... ( this is just my opinion)...
