breaking up with my fiance while ttc

i think i need to break up with my fiancé🥺

let me start by saying i absolutely adore him and really cant imagine my life without him. however there is a situation that is happening that is making me think we will need to separate.

we were due to move in together but couldn’t find somewhere good and then covid happened so are still at his parents place. we started ttc 5months ago and still havent managed to move out yet even though that was our plan (please no judgements on this)

anyway his mum has no said she is planning on moving away and wants to be as far away from this area as possible (bad memories) my partner will be going with and looking at properties in a similar or close by area to his mum. however all my family are local to the area we are in now.

i cant see myself moving more than 2hrs max away from my own family as i see them daily and we are super close. his mum has already made it clear if she finds a house that is ie. 7 hours away she will move. my fiancé is still going ahead with the idea.

how do i bring about stopping ttc and house hunting here? i really cant imagine having a baby now and not being together. is it wrong im thinking of leaving him?

i cannot move 7hrs and and he will not stay behind near my family. halfway is potentially an option depending on how far his mum moves. she hasn’t bought a house yet but he refuses to talk about it properly with me.

i feel heartbroken, sad, confused, angry. im 9dpo now and kind of hoping im not pregnant so we have time to discuss this properly😔

any advice??
