I’m unhappy in my relationship. The reality is I’ve been treated badly for years and while he is not as spiteful anymore he is very lazy and does the bare minimum all of the time. He doesn’t work at the moment, but doesn’t help anymore at home. We live with our two boys and his two girls but I’m the main carer for all kids, while also working full time. Everytime I ask him to leave I have extreme guilt about the kids. I know I am not happy and I almost feel as though I’m starting to resent him. Everytime we argue all the horrible things race through my head and it feels like a big barrier. What can I do?
