I'm coming to terms with dealing with everything on my own and it's tough! Not because I'm on my own I'm not, I've been with my partner for a very long time, we have a 12 year old & 3 year old.I'd say I've just got on and done everything since my oldest was little as we would argue every time I'd ask him to do stuff, I did all the clubs, pick ups and drop offs, juggle all the responsibility and work full time. He started up his own business which I supported us financially and carried the load of parenting whilst he worked alot.He couldn't support me on mat leave, didn't do night night feeds, my baby didn't sleep for over a year, up every hour and I felt broken very close to a breakdown and he didn't once help, he was moody, angry hated it if I met up with family, arranged a girls night he text me to not come home at 10 o clock. He smashed my wardrobe door off when I went out to my sisters with my 2 children whilst he slept.I come to a point where I set boundaries and try to get him to help me, I must have the conversation every week now since having a 2nd child 3 years ago things have just gotten so much worse, he becomes better and does a little bit more like tea once or washes the pots then just reverts back to saying it's hard and it's because I wanted a big job that's too much for me, even though I needed to go back to work because he got himself into alot of debt when I was on mat leave and now wants to remortgage to pay his debts off.I've said I'm going to separate if things don't change and he says this will be awful for the children and that he does stuff.At the moment my little one has started preschool after being with a childminder, I'm working full time around arranging settles, for a week, no family to help doing drio off and pick ups, I've been upset saying how I am going to do this whilst working and he just says everyone has to do this it's hard. So I'm sat here with a full diary with a toddler bouncing around me whilst I work, it's unmanageable.I'll then, clean, make tea, do food shop, baths, sports club, have full responsibility over both children's school apps, arrange all financial bills, and just take the load. I've been asked to work abroad with my role for a week and my partner has said that's not doable. I'm the breadwinner and pay more for the bills etc, i just don't know what to do other than call it a day, it's either the job or relationship I'm miserable and feel so bad for the children.He does do bits, like read to our 3 year old at night and bring them a drink in morning plus general diy.
