What is best for my son?

[Tarmacgreen]

My son has lived with his dad since April, he's happy there but misses me and I desperately miss him. He has always lived with me until April when an incident caused a huge row, three years ago we moved in with my new partner he doesn't get on with him at all. My dilemma is that he is 15 and as of Sept will need to travel 80 miles a day to school and back - he will get a lift part of the way but I think it's too much. I have thought of moving out on my own but this will mean leaving my partner and trying to cope with renting as financially i'm not secure.
I feel like I've completely failed him and really don't know what to do can anyone give me advice I'm trying to be practical but emotion always takes over.

Would it not make more sense to move to a school near his Dad's ?
I'm inclined to agree that a 40 mile each way journey is impractical, but I don't think a 15 yr old should be dictating who you live with either.

Why would you have to move, not your partner?

I'm not an advocate of moving schools, but maybe this is an option if he is going to stay with his Dad? 80 miles is a lot of travelling and having to cope with the move and his GCSE's.

Why doesn't he get on with your partner? Is it down to DS or DP or a bit of both?

Thanks for all your replies.
I agree it's too far but he can't move schools as he is in his final
year and it would be too disruptive. He hopes to go to sixth form near where his
father lives next year.
My son hasn't asked me to move or anything of the sort, it's me who can't cope with the idea of him trying to cope. I don't own the house it's my partners so I can't tell him to move out either. It's very easy for me to just do nothing and hope that he copes but I feel I'd be letting him down.
