My heart is breaking, my son split from his ex 6 years ago, everything has been fine, my son has collected his 2 daughters, one age 6yrs and one is 11yrs every weekend on Friday night and taken them back Saturday night, he has been giving his ex money every week but he has recently fallen on very hard times and is unable to give her money at the moment. I have been giving money to them so my son can get his things in order but I found out that the money is not being spent on my grandchildren because they were coming in old clothes and shoes with holes in, so I decided to spend it on the girls instead of giving cash to his ex, we have now been stopped from seeing the girls although they have said that it is the girls decision not to come. I know that there is a lot of abusive language used by the ex's parents in front of the 2girls and I cannot do anything about it mainly bececause I don't want the girls to be upset by me saying anything to his ex or her parents. The last time I saw the girls was 3 weeks ago when I went to pick them up because my son was at work, his ex's mother shouted very bad language at me and would not let me take the girls they also called my son horrible names, all this was in front of the 2 girls, I did not say anything to them because it would upset the girls more.please help me with this problem.
