So it would mean a change of schools for one child. And a complete switch of friends?
Has either child already done the big transition to secondary? I’m assuming the 12 year old has.
Bluntly? Based on what you’ve said, I wouldn’t move in together. Especially if both children are already in secondary and have done that transition. The pandemic has been super tough on all kids. The last thing they need is a school move.
Secondly from the sound of things, if it’s already stressful during the little time you spend together, what do you think it would be like living together 24/7? Throw in teen hormones and you’re looking at an absolute nightmare situation.
Aside from those logistics, have you and your partner sat down and discussed how you each parent? Discipline? Are you on the same page? How would you tackle a fight between the boys?
He’s financially better off than you? Ok, what does that look like? That would mean ( I assume) he can afford nicer things/ holidays/ toys for his children. Would there be financial parity in how the children are treated or not?
He’s buying a house. What does that look like? Does he want to buy with you? Is he expecting 50/50? What happens if you make this move and the relationship breaks down? How are you (and he) financially protected?
These are all HUGE conversations, that can be ducked when living apart / dating.
But critical to have before living together. And I had all of them and thus ruled out living with my ex. Why? We are not on the same page re parenting. Financially I am much better off than him and he could not come to the table as a mature adult and have difficult conversations (namely that my assets thus far accumulated are for my children and not to provide him / his children a comfortable lifestyle). So there would have been financial disparity as I would want to take my children on nice holidays and I have zero intention of paying for his.
More to the point, the children get along (they’re civil) but that’s about it. My children prefer their time with me and would not want to share their home with my exes children.
I’m glad you’re asking yourself what’s right. As too many people plough headfirst into these situations and years later are regretting having ever taken the plunge.
I’m asking myself if I am happy to continue this way with my ex (and reconcile) or simply move on and accept that I either need to stay single/ date but not involve the children/ date someone with no children or grown up children. I won’t date anyone else with kids the same age as mine (or younger).
