Tired affff….

Need some advice/vent… A little back story (super short) My bf and his friends love to go to Vegas to gamble. His friends planned to go now in October and he told me he forsure wasn’t going to go due to money. Yesterday he told me he was going to a city a few hours away to a shooting range because there are some fires near us so the ones close r closed (a truth). However. He didn’t take his own gun(red flag) saying he would use his friends. He left yesterday at 9am. It is currently almost 8 pm the next day. I would bet money he went to Vegas. He hasn’t answered any calls or texts at all. My best friend for forever offered for us to live with her and I’m seriously considering. This isn’t the first time he has done this. Idk what to do…* keep in mind we have 4 kids. Ages 6,5,4 and 1 😔
