Clash with parents

Haiz ever since My son was born I keep having clashes with my parents as I’m staying with them. My bto will only be ready ard 2023-2024. My hubby is pr so his family is not here. Tried for pphs once and is trying again this month. We did considered getting resale while I was pregnant with my son but didn’t as I was only working part-time then and couldn’t get much grant. Sld I give up the bto(alr paid deposit) and just go for resale? I’m currently pregnant with a second one and they are not keen to help me take care of my second one. They are only willing to help me take care of my son but nope I’m not going to let us be separated…..
