Im so sorry to hear you are going through something like that especially with children involved i know what its like and its tough. As a parent its natural to want to protect them, but my partner sees this is as me smothering them. He has so many things to say about how I should parent. Yet when we first me met and i had been a single mum he said i was an amazing mum and the kids were lucky to have me. He wished the kids were his. I can see he doesnt think that now from how he is.
Being trapped like that is an awful situation for you, and with you saying your partner sleeps all day. Mine does this too. Sometimes 18 hours at a time, usually 1-2 days a week but even more since lockdown, im practically on my own anyway. It causes so much frustration i cant even explain it, my daughter especially gets upset asking him to get up etc. He doesnt care. Hes accused me of allsorts apparently iv been with my next door neighbour, a guy who came to do maintenance at my property, he thinks i dont have a sexual relationship with him because im trying to get rid of an std when in reality im so hurt by him i cant bring myself to be emotionally engaged in anything to do with him. Its like iv had to detatch myself, because i would have honestly had a break down.
