I left home at 18 and got a house with my child and ex. I split with my ex a few years later and met (now) DH about two weeks later. He was in the army and quickly 'moved in' with me away from his parents as he was spending all his weekends home with me.
Through the week, my child would be in bed at 7 and I wouldn't go out on an evening as friends would be busy with their other halves and/or also had children. I paid all the bills, ran the household etc. (eventually went to Uni too but that's not completely relevant). My DH took on the father role almost immediately and weekends were family orientated.
Before my DH left the army, he did some 6 month tours away.
During one tour, I needed £500 to pay a bailiff or something (I can't quite remember, more than 12 years ago) but our finances were shared so it was more a notification to him than a request. (FWIW, bailiffs, debt etc. is no longer an issue)
He recently had a debate with someone that it is easy to live alone. He argues that in the army he lived alone. He didn't, he shared a room with at least 3 others. He didn't have to arrange to pay rent, council tax, utilities, food, do housework such as cleaning a bathroom etc. as it came directly from his wages or was sorted for him. His mother did his washing until he moved in with me then it would be done by him or me.
He says if he had lived completely alone he wouldn't have to worry about what I spend money on and would just pay his bills and have loads left. He wouldn't get lonely because he would go to his friends/families house. I said you can't do that on an evening with kids in bed, to which he replied he would have them come to him instead. (He's right, he often has friends around).
AIBU that it frustrates me though that he claims living alone is easy and really he hasn't ever done it! He says neither have I because I had him bringing in money! I explained it's not just financial contribution we are discussing!
