ils have been divorced for approaching 30 years. Fil remarried and dh has a half sister who is early 20's.
Over the past few years I have noticed that fil and mil spend a fair bit of time together. More than what I consider "normal". Fil chooses to take mil places to the detriment of step mil - eg dc1 christening. Fil brought mil rather than step mil, saying she had flu. Some time later step mil said that they had rowed and he chose mil over her.
Fil has also brought mil to visit rather than step mil. Mil doesnt drive, fil and step mil both drive.
Recently, I have discovered mil and fil have a joint bank account which allows fil to filter money away from stepmil.Fil was always fair to mil in the divorce and with his child support when dh and his siblings were young. They are all mid 30's and older now.
Step mil now takes long holidays with her family and leaves fil home alone as it were and he spends a good chunk of his time with his ex wife. Visiting her, doing jobs for her etc.
I feel desperately sorry for step mil as I do not think she is aware of the extent to which fil / mil behaviour enables the other.
Dh thinks the carry on is slightly strange but it is on his normal range as they are his parents.
I think when it comes to our children that they need to know they are not together and in fact fil has a wife who isnt mil! We live away from them and so do not see them every week.
Dh thinks I am not being reasonable. I said when we visit his mil, fil should not be there. I personally think mil and fil will get back together at some point but they are currently not together so the dc seeing them together leads to more confusion.
So, is this normal or am I just being a bit odd about it?
