I'll try and keep this short.
My ex and I have 2 DS's aged 13 and 10.
Both DS's stay with their DF 3 nights out of 10. This is when I am in working in the evenings although I work full time.
Me ex and I split 5 years ago due to his infidelity. To be honest it was a relief, my ex was like a third child and not a particularly supportive partner - I made all decisions and took care of everything at home.
Since the split my ex has had a child with his FWB. They tried to make a go of it and this brought a whole load of issues including threats of suicide from the mother in front of my DS's (DS (10) was worried that she would die) and then the end of that relationship which dragged on for a while - they were told the relationship ended because the mother was crazy - the poor woman probably had PND. What was also tricky was that my DS's were completely confused by the pregnancy in the first place because they didn't know about their DF's relationship.
My ex lives a 10 minute walk away. His house is a mess and along with that he has a cat and dog. DS said the puppy shits inside, the house also has an aroma of cat urine. Both DS's share a room which they dislike, although I realise this is perfectly acceptable. Their DF does not buy them clothes to wear when at his - I used to pack a bag but would never get their stuff back so resorted to giving him clothes for them to wear when they are there. These clothes are now too small.
Since the split I have met my DP 2.5 years ago. We don't live together but plan to do so in the next year. He's part of a lot of our lives - we have days out together, holidays and just spend time in each other's company. My DS's say they enjoy him being around and look forward to spending time with him and his kids. He's a steady person in their lives and reliable too.
I started to notice changes in my DS (10) in the summer. He started to get obsessive over going to toilet and this has manifested in a fear of not being able to use the toilet at all times. Its affected everything - leaving for school, his time in school, him playing sport and the embarrassment he feels about it. He's also got an issue with what time it is. The dr has completed tests and theres nothing medically wrong. His school SENCO has completed a multi-agency referral and he is about to start school counselling next week. At home he says he gets these feelings of sadness that come over him. He'd cry and not tell me why and these crying sessions would go on for quite some time. He eventually told me why he was crying, I think when he could make sense of it all, and said its because he doesn't like being at his DF's.
He said the reasons are; his little brother is there, aged 2 and he feels an overwhelming responsibility to look after him. He said his dad asks him to look after him too although I'm not sure if this us something he feels himself. He said they don't do anything, just watching TV; DF vapes in the house and he doesn't like it; he has few toys (his DB said he has a few cars and a lego set); he also said his DF gets angry (never violent) I think what he means by this is his DF is very emotional and cannot hide any emotion and he picks up on it.
My DS(13) agrees with a lot of what DS (10) says. He said he prefers to stay with me but feels sorry for his dad. He's got the ability not to pick up on the cues because he just lives in his own world.
DS(10) is refusing to stay with his dad. I've swapped shifts, used my parents and DP has helped. With forward planning I can take care of him my end. DS(13) is still staying with his dad and I'm supportive of this if that's what he wants.
I'm just at a loss with knowing the best for DS(10). I want to tell his DF that at the moment overnights should stop completely- this will remove DS's anxiety and then we can make tentative steps when hes feeling stronger. My concerns are that his relationship with his DF will be on a downward slope and that in the long term it will not help him. I also don't want to be 'that's mum.
Does anyone have any advice. And sorry this was such an essay!
