Love / I am very much confused about My Polish Gf - Long distance relationship [12]

In general how much I can trust a girl who uses to party with guys but hiding from her X husband? She said she isnt a party girl anymore but she go out everyday to her parents and she doesnt take my calls on every alternate day there ,she doesnt come to video call as she doesnt take it easily ,she is an introvert but I can see so many signs of an extrovert,I am really cofused .......

How Much I can trust someone in a Long distance relationship?
