Ex Dp and I have been living in same house for three years (since we split) as its cheaper than running two houses and it's more convenient for childcare (none of us have other family living nearby to help out). We have 3 dc's aged 7, 10 and 12. Exdp and I share the childcare as if we were living apart eg he has sole charge over them every other weekend and on one weekday every week. This all largely works because our house is large enough for exdp and I to have our own bedroom and living room each, so we have our own space. Neither of us is seeing anyone else. Ex dp is bitter that I left him 3 yrs ago and whilst we don't have many arguments in front of the kids, the relationship on a day to day level is not great and we are not on friendly terms, don't speak to each other unless really have to and so on. My question is this: are exdp and I setting the kids a bad example as to how normal loving adult relationships should be? The kids know exdp and I aren't together any longer but they all say they are happy for exdp and I to still live under the same roof in spite of the fact exdp and I are not wanting to be anywhere near each other. Will the kids fall into equally bad relationships when they are older? Is better for the kids to live in separate single parent /one adult households? I don't have time or inclination to find another dp so even if I lived on my own with the kids, would they think this is normal and not aspire to finding loving partners for themselves when older?
