Wife more inclined towards friends society and photo shoot modelling

Hi! Well one needs courage to type his/her feelings he/she is going through.No issues to resolve one has to.My queries and details as follows. 1.I dare to marry a girl of single parent that is single mother who got separated from her husband due to different reasons . 2.Today after 16 years of marriage she left the house on disputes as she needs to do modelling which i dint like, hence she is asking for mutual divorce.Three days before infact she has already discussed the same with her friends or her mother who is also divorced. 3.Basic area of our conflict is her extrovert behaviour with all be it women or gents. 4.She used to remain out till 9 or 9:30 in the evenings to spend time with the society and hardly pays attention to me.Moreever many a times she has kicjed me out if the room.Initially she took one room now she took one more room for so called chanting with others where my access is not possible . 5.Major issue that i couldnt support her financially becuase i lost huge amount in shares hebce she is managing the child fees but all other household rxpenditure is done by my father. 6.She has raised complaints against me un the police station and taken back on mutual agreement that i will allow her whtever she wants to do. 7.I am also ready for mutual divorce but worried about the child custody if given to her as she is financially strong and on the other hand she has not much time to see the child as she is always busy in one or another thing. 8.Kindly advise can i retain both if not both den how can child custody.
