Thanks to all who commented on my previous post.
After a really tough couple of weeks, DP has come to terms with me pulling out of what we thought would be our perfect first home together.
I really didn’t think our relationship would survive as he was both shocked and deeply hurt, but we seem to be getting there.
He was a bit taken aback that I still wanted to go through with my house sale ( for lots of reasons that he does understand), but hopefully is reassured that, once the children are all settled I really hope we will finally settle down together, and that I am not doing this to start a new life on my own.
I have involved him in helping me choose somewhere, and my intention was to find somewhere that would be easy to sell in the future.
Houses in my price range are literally only on the market for a couple of days at the moment, so when I saw a newish, immaculate house came onto the market earlier this week, I viewed it, loved it and put an offer in the next day which was accepted.
It’s all felt a bit surreal but it’s nearer to DP, on an estate he’s familiar with as he used to live there and will mean I can pay off most of my mortgage, pay off a small debt, not have to do a thing to it and it will hopefully make a bit of money so that I can resell in a couple of years when we can finally be together.
For now the future looks rosy 
Thanks again to you all
