I feel sick to my stomach. I have a nearly 3 year old son. Me and his dad split couple of months ago because of so many reasons but basically the relationship made me miserable and he has MH issues he refuses to do anything about and he is a very angry person. I have my own home so he moved out. This wasn't a decision made lightly it had been coming and I exhausted every other option. Since he left he has given me £35 a week. I work 30 hours a week and he works a lot more and earns probably three times as much as me. At first I accepted the £35 for some reason I felt guilty as the house was mine and he had to leave. I have since brought it up again and he goes beserk but I'm always struggling. He has my son once a week usually in the day time and thats it. The one day I needed him for something this week he was sleeping with someone else and this killed me. It just made me realise how little I've meant to him and how he will drop me and my son like a hat and I've been an idiot. Anyway I'm writing this in anger but considering going to the CSA. The calculator says I would be entitled to £80 a week. I'm just stupidly feeling guilty about it without speaking to him first. Help 😩.
