I separated from my wife 2mnths ago and she hasn’t allowed me to see my child since. There’s no paperwork filed and now she’s blocked my number. WDID?

You will need to get a court ordered possession schedule by filing for divorce and asking for a possession order.  You should request Temporary Orders and get a hearing set for Temporary Orders.  At the Temporary Order hearing you would either work out a schedule with your wife or, more likely, the court will order a schedule for you to have possession of your children.  Texas has a Standard Possession Order and an expanded Standard Possession Order.  You will have your children more overnights if you choose the expanded Standard Possession Order.  The court will want you to have appropriate living arrangements and beds for the girls.  When the possession schedule is in an order signed by the court, you need to follow it exactly as stated.  Pick up the girls on the day, at the time and place stated in the order.  Then if your wife does not comply you will be able to ask the court to enforce the possession order and hold your wife in contempt of court.  I wish you the best.
