When my ex left me for another women we came up to agreement of child maintenance for our two children, he’s was employed and kept up the payments even though he would Complain he has hardly has any money left after debts etc.. he then became self employed and was late on Payments then couldn’t pay etc, so me being nice I accepted he was struggling and said it was ok. Then March with the lockdown of COVID 19 he said he had no work so still never received a penny since feb even though he promised he would help support the kids if he could, it’s nearly been 6 months now and nothing. My problem is my ex has been spotted working and he set up his own Carpentry Fb profile Advertising and has had a few jobs ie kitchen/bathrooms he’s done for his customers, my daughters birthday was March and she didn’t have a lot From him and he promised to take her clothes shopping when he had some money month after was his girlfriends birthday and he bought her a puppy. his own mother said he’s working but not sure if she knows her son hasn’t supported his children for a while. I know he’s working and my gut feeling is he’s earning money but doesn’t want to provide for his kid. his gf seems like she’s always on the want and I believe he’s doing her house up of which he does live in, even though I gave him out family car bk to which he sold for £8000 so should Be enough to do up a rented property. I can’t believe the man I once was with is being like This and I’m too scared to contact him since he left I have panic attacks even if someone mentions his name. My children don’t have a good relationship with there dad as they were pushed out His gf came first and even when they Kids tried his gf would brag what there dad would Buy for her daughter. I very much appreciate any advice.
