DP and I are engaged and planning to marry next spring at which point he and his two DCs, 7 and 10, will move in with me and my DSs, 5 and 3. DP is understandably reluctant to move into my house as it used to be where I lived with ex DH and he says it doesn't feel like his but, financially, it makes sense to stay put plus we ideally need 5 bedrooms, which the house has, and if we move would be unlikely to be able to find or afford a 5 bedroom house due to moving costs and scarcity of 5 bed houses where we live. At the moment my DSs have a big room each. There is a big (double) spare room and a smaller double/single room which his children would have. He has them 50% of the time so they would spend Weds-Fri nights with us. DP is not happy that one of his DCs would have a smaller room. It is much smaller that the others but still a good size. In addition, DP currently has a one bedroom flat and when his DCs are with him they share a room (he sleeps on the floor of their room when they stay) and they also share a room at his ex's so they would already be better off as they will at least have a room each especially as his daughter is 10 and really needs her own room rather than sharing with her dad/brother. I can understand that DP wants them all to be treated equally but do feel he is being a bit precious and unreasonable over this especially as his DSs are only there 50% of the time. In addition, I own the house and when he moves in he has no equity or other money to contribute. We will probably remortgage then but I will still own and be paying for 80% of the house. We did start to look at other houses in case we do decide to move but DP seems to think that all DCs need to have an equal size room each even though his DCs are there 50% of the time. Am I being unfair? I feel very strongly that I don't want to move in any event. Seems pointless to waste time and money and go through all that stress and hassle just DP feels more at home. I think also that I feel more secure staying in my own place. Again, am I being unreasonable and selfish to be reluctant to move? I do understand DP's feelings on this but just seems like too great a risk for me and my DCS, especially having just been through a difficult divorce where I fought tooth and nail to stay in this house.
